Form Helper

- -

The Form Helper file contains functions that assist in working with forms.

- - -

Loading this Helper

- -

This helper is loaded using the following code:

-$this->load->helper('form'); - -

The following functions are available:

- - - -

form_open()

- -

Creates an opening form tag with a base URL built from your config preferences. It will optionally let you -add form attributes and hidden input fields, and will always add the attribute accept-charset based on the charset value in your config file.

- -

The main benefit of using this tag rather than hard coding your own HTML is that it permits your site to be more portable -in the event your URLs ever change.

- -

Here's a simple example:

- -echo form_open('email/send'); - -

The above example would create a form that points to your base URL plus the "email/send" URI segments, like this:

- -<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send" /> - -

Adding Attributes

- -

Attributes can be added by passing an associative array to the second parameter, like this:

- - -$attributes = array('class' => 'email', 'id' => 'myform');
-
-echo form_open('email/send', $attributes); - -

The above example would create a form similar to this:

- -<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send"  class="email"  id="myform" /> - -

Adding Hidden Input Fields

- -

Hidden fields can be added by passing an associative array to the third parameter, like this:

- - -$hidden = array('username' => 'Joe', 'member_id' => '234');
-
-echo form_open('email/send', '', $hidden); - -

The above example would create a form similar to this:

- -<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send">
-<input type="hidden" name="username" value="Joe" />
-<input type="hidden" name="member_id" value="234" /> - - -

form_open_multipart()

- -

This function is absolutely identical to the form_open() tag above except that it adds a multipart attribute, -which is necessary if you would like to use the form to upload files with.

- -

form_hidden()

- -

Lets you generate hidden input fields. You can either submit a name/value string to create one field:

- -form_hidden('username', 'johndoe');
-
-// Would produce:

-<input type="hidden" name="username" value="johndoe" /> - -

Or you can submit an associative array to create multiple fields:

- -$data = array(
-              'name'  => 'John Doe',
-              'email' => 'john@example.com',
-              'url'   => 'http://example.com'
-            );
-
-echo form_hidden($data);
-
-// Would produce:

-<input type="hidden" name="name" value="John Doe" />
-<input type="hidden" name="email" value="john@example.com" />
-<input type="hidden" name="url" value="http://example.com" /> - - - - -

form_input()

- -

Lets you generate a standard text input field. You can minimally pass the field name and value in the first -and second parameter:

- -echo form_input('username', 'johndoe'); - -

Or you can pass an associative array containing any data you wish your form to contain:

- -$data = array(
-              'name'        => 'username',
-              'id'          => 'username',
-              'value'       => 'johndoe',
-              'maxlength'   => '100',
-              'size'        => '50',
-              'style'       => 'width:50%',
-            );
-
-echo form_input($data);
-
-// Would produce:

-<input type="text" name="username" id="username" value="johndoe" maxlength="100" size="50" style="width:50%" /> - -

If you would like your form to contain some additional data, like Javascript, you can pass it as a string in the -third parameter:

- -$js = 'onClick="some_function()"';
-
-echo form_input('username', 'johndoe', $js); - -

form_password()

- -

This function is identical in all respects to the form_input() function above -except that it uses the "password" input type.

- -

form_upload()

- -

This function is identical in all respects to the form_input() function above -except that it uses the "file" input type, allowing it to be used to upload files.

- -

form_textarea()

- -

This function is identical in all respects to the form_input() function above -except that it generates a "textarea" type. Note: Instead of the "maxlength" and "size" attributes in the above -example, you will instead specify "rows" and "cols".

- - -

form_dropdown()

- -

Lets you create a standard drop-down field. The first parameter will contain the name of the field, -the second parameter will contain an associative array of options, and the third parameter will contain the -value you wish to be selected. You can also pass an array of multiple items through the third parameter, and CodeIgniter will create a multiple select for you. Example:

- -$options = array(
-                  'small'  => 'Small Shirt',
-                  'med'    => 'Medium Shirt',
-                  'large'   => 'Large Shirt',
-                  'xlarge' => 'Extra Large Shirt',
-                );
-
-$shirts_on_sale = array('small', 'large');
-
-echo form_dropdown('shirts', $options, 'large');
-
-// Would produce:
-
-<select name="shirts">
-<option value="small">Small Shirt</option>
-<option value="med">Medium Shirt</option>
-<option value="large" selected="selected">Large Shirt</option>
-<option value="xlarge">Extra Large Shirt</option>
-</select>
-
-echo form_dropdown('shirts', $options, $shirts_on_sale);
-
-// Would produce:
-
-<select name="shirts" multiple="multiple">
-<option value="small" selected="selected">Small Shirt</option>
-<option value="med">Medium Shirt</option>
-<option value="large" selected="selected">Large Shirt</option>
-<option value="xlarge">Extra Large Shirt</option>
-</select> - - -

If you would like the opening <select> to contain additional data, like an id attribute or JavaScript, you can pass it as a string in the -fourth parameter:

- -$js = 'id="shirts" onChange="some_function();"';
-
-echo form_dropdown('shirts', $options, 'large', $js); - -

If the array passed as $options is a multidimensional array, form_dropdown() will produce an <optgroup> with the array key as the label.

- -

form_multiselect()

- -

Lets you create a standard multiselect field. The first parameter will contain the name of the field, -the second parameter will contain an associative array of options, and the third parameter will contain the -value or values you wish to be selected. The parameter usage is identical to using form_dropdown() above, -except of course that the name of the field will need to use POST array syntax, e.g. foo[].

- - -

form_fieldset()

- -

Lets you generate fieldset/legend fields.

-echo form_fieldset('Address Information');
-echo "<p>fieldset content here</p>\n";
-echo form_fieldset_close(); -
-
-// Produces
-<fieldset> -
-<legend>Address Information</legend> -
-<p>form content here</p> -
-</fieldset> -

Similar to other functions, you can submit an associative array in the second parameter if you prefer to set additional attributes.

-

$attributes = array('id' => 'address_info', 'class' => 'address_info');
- echo form_fieldset('Address Information', $attributes);
-echo "<p>fieldset content here</p>\n";
-echo form_fieldset_close();
-
-// Produces
-<fieldset id="address_info" class="address_info">
-<legend>Address Information</legend>
-<p>form content here</p>
-</fieldset>

-

form_fieldset_close()

-

Produces a closing </fieldset> tag. The only advantage to using this function is it permits you to pass data to it - which will be added below the tag. For example:

-$string = "</div></div>";
-
-echo form_fieldset_close($string);
-
-// Would produce:
-</fieldset>
-</div></div> -

form_checkbox()

-

Lets you generate a checkbox field. Simple example:

-echo form_checkbox('newsletter', 'accept', TRUE);
-
-// Would produce:
-
-<input type="checkbox" name="newsletter" value="accept" checked="checked" /> -

The third parameter contains a boolean TRUE/FALSE to determine whether the box should be checked or not.

-

Similar to the other form functions in this helper, you can also pass an array of attributes to the function:

- -$data = array(
-    'name'        => 'newsletter',
-    'id'          => 'newsletter',
-    'value'       => 'accept',
-    'checked'     => TRUE,
-    'style'       => 'margin:10px',
-    );
-
-echo form_checkbox($data);
-
-// Would produce:

-<input type="checkbox" name="newsletter" id="newsletter" value="accept" checked="checked" style="margin:10px" /> - -

As with other functions, if you would like the tag to contain additional data, like JavaScript, you can pass it as a string in the -fourth parameter:

- -$js = 'onClick="some_function()"';
-
- echo form_checkbox('newsletter', 'accept', TRUE, $js) - - -

form_radio()

-

This function is identical in all respects to the form_checkbox() function above except that it uses the "radio" input type.

- - -

form_submit()

- -

Lets you generate a standard submit button. Simple example:

-echo form_submit('mysubmit', 'Submit Post!');
-
-// Would produce:
-
-<input type="submit" name="mysubmit" value="Submit Post!" /> -

Similar to other functions, you can submit an associative array in the first parameter if you prefer to set your own attributes. - The third parameter lets you add extra data to your form, like JavaScript.

-

form_label()

-

Lets you generate a <label>. Simple example:

-echo form_label('What is your Name', 'username');
-
-// Would produce: -
-<label for="username">What is your Name</label> -

Similar to other functions, you can submit an associative array in the third parameter if you prefer to set additional attributes.

-

$attributes = array(
-    'class' => 'mycustomclass',
-    'style' => 'color: #000;',
-);
- echo form_label('What is your Name', 'username', $attributes);
-
-// Would produce:
-<label for="username" class="mycustomclass" style="color: #000;">What is your Name</label>

-

form_reset()

- -

Lets you generate a standard reset button. Use is identical to form_submit().

- -

form_button()

- -

Lets you generate a standard button element. You can minimally pass the button name and content in the first and second parameter:

- -echo form_button('name','content');
-
-// Would produce
-<button name="name" type="button">Content</button> - - -Or you can pass an associative array containing any data you wish your form to contain: - -$data = array(
-    'name' => 'button',
-    'id' => 'button',
-    'value' => 'true',
-    'type' => 'reset',
-    'content' => 'Reset'
-);
-
-echo form_button($data);
-
-// Would produce:
-<button name="button" id="button" value="true" type="reset">Reset</button> - - -If you would like your form to contain some additional data, like JavaScript, you can pass it as a string in the third parameter: - -$js = 'onClick="some_function()"';

-echo form_button('mybutton', 'Click Me', $js); - - - -

form_close()

- -

Produces a closing </form> tag. The only advantage to using this function is it permits you to pass data to it -which will be added below the tag. For example:

- -$string = "</div></div>";
-
-echo form_close($string);
-
-// Would produce:
-
-</form>
-</div></div> - - - - - -

form_prep()

- -

Allows you to safely use HTML and characters such as quotes within form elements without breaking out of the form. Consider this example:

- -$string = 'Here is a string containing "quoted" text.';
-
-<input type="text" name="myform" value="$string" /> - -

Since the above string contains a set of quotes it will cause the form to break. -The form_prep function converts HTML so that it can be used safely:

- -<input type="text" name="myform" value="<?php echo form_prep($string); ?>" /> - -

Note: If you use any of the form helper functions listed in this page the form -values will be prepped automatically, so there is no need to call this function. Use it only if you are -creating your own form elements.

- - -

set_value()

- -

Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function. -The second (optional) parameter allows you to set a default value for the form. Example:

- -<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" /> - -

The above form will show "0" when loaded for the first time.

- -

set_select()

- -

If you use a <select> menu, this function permits you to display the menu item that was selected. The first parameter -must contain the name of the select menu, the second parameter must contain the value of -each item, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE).

- -

Example:

- - -<select name="myselect">
-<option value="one" <?php echo set_select('myselect', 'one', TRUE); ?> >One</option>
-<option value="two" <?php echo set_select('myselect', 'two'); ?> >Two</option>
-<option value="three" <?php echo set_select('myselect', 'three'); ?> >Three</option>
-</select> - - - -

set_checkbox()

- -

Permits you to display a checkbox in the state it was submitted. The first parameter -must contain the name of the checkbox, the second parameter must contain its value, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE). Example:

- -<input type="checkbox" name="mycheck" value="1" <?php echo set_checkbox('mycheck', '1'); ?> />
-<input type="checkbox" name="mycheck" value="2" <?php echo set_checkbox('mycheck', '2'); ?> /> - - -

set_radio()

- -

Permits you to display radio buttons in the state they were submitted. This function is identical to the set_checkbox() function above.

- -<input type="radio" name="myradio" value="1" <?php echo set_radio('myradio', '1', TRUE); ?> />
-<input type="radio" name="myradio" value="2" <?php echo set_radio('myradio', '2'); ?> /> - - - - -
