The extended class is a part of my validate library but i release it as a stand alone class too.
The methods of this class are input sensitive. The input can come from $_POST or $_GET. Save the code as MY_form_helper.php in the application/helpers directory. And load the form helper as usual.
<?php
function form_hidden($name, $value = '')
{
if ( ! is_array($name))
{
$value = (isset($_POST[$name]))?$_POST[$name]:((isset($_GET[$name]))?$_GET[$name]:$value);
return '<input type="hidden" name="'.$name.'" value="'.form_prep($value).'" />';
}
$form = '';
foreach ($name as $name => $value)
{
$value = (isset($_POST[$name]))?$_POST[$name]:((isset($_GET[$name]))?$_GET[$name]:$value);
$form .= '<input type="hidden" name="'.$name.'" value="'.form_prep($value).'" />';
}
return $form;
}
function form_input($data = '', $value = '', $extra = '')
{
$name = ( ! is_array($data))?$data:((isset($data['name']))?$data['name']:'');
$value = (isset($_POST[$name]))?$_POST[$name]:((isset($_GET[$name]))?$_GET[$name]:$value);
$defaults = array('type' => 'text', 'name' => (( ! is_array($data)) ? $data : ''), 'value' => $value, 'maxlength' => '500', 'size' => '50');
return "<input ".parse_form_attributes($data, $defaults).$extra." />\n";
}
function form_textarea($data = '', $value = '', $extra = '')
{
$name = ( ! is_array($data))?$data:((isset($data['name']))?$data['name']:'');
$defaults = array('name' => (( ! is_array($data)) ? $data : ''), 'cols' => '90', 'rows' => '12');
if ( ! is_array($data) OR ! isset($data['value']))
{
$val = (isset($_POST[$name]))?$_POST[$name]:((isset($_GET[$name]))?$_GET[$name]:$value);
}
else
{
$val = (isset($_POST[$name]))?$_POST[$name]:((isset($_GET[$name]))?$_GET[$name]:$data['value']);
unset($data['value']); // textareas don't use the value attribute
}
return "<textarea ".parse_form_attributes($data, $defaults).$extra.">".$val."</textarea>\n";
}
function form_dropdown($name = '', $options = array(), $selected = '', $extra = '')
{
if ($extra != '') $extra = ' '.$extra;
$form = '<select name="'.$name.'"'.$extra.">\n";
foreach ($options as $key => $val)
{
$key = (string) $key;
$val = (string) $val;
$name = str_replace('[]','',$name);
$send = (isset($_POST[$name]))?$_POST[$name]:((isset($_GET[$name]))?$_GET[$name]:$selected);
$sel = (is_array($send) && in_array($key, $send))?' selected="selected"':(($key == $send)?' selected="selected"':'');
$form .= '<option value="'.$key.'"'.$sel.'>'.$val."</option>\n";
}
$form .= '</select>';
return $form;
}
function form_checkbox($data = '', $value = '', $checked = FALSE, $extra = '')
{
$name = ( ! is_array($data))?$data:((isset($data['name']))?$data['name']:'');
$defaults = array('type' => 'checkbox', 'name' => (( ! is_array($data)) ? $data : ''), 'value' => $value);
if (is_array($data) AND array_key_exists('checked', $data))
{
$checked = (isset($_POST[$name]))?TRUE:((isset($_GET[$name]))?TRUE:$data['checked']);
if ($checked == FALSE)
{
unset($data['checked']);
}
else
{
$data['checked'] = 'checked';
}
}
$checked = (isset($_POST[$name]))?TRUE:((isset($_GET[$name]))?TRUE:$checked);
if ($checked == TRUE)
$defaults['checked'] = 'checked';
else
unset($defaults['checked']);
return "<input ".parse_form_attributes($data, $defaults).$extra." />\n";
}
function form_radio($data = '', $value = '', $checked = FALSE, $extra = '')
{
if ( ! is_array($data))
{
$data = array('name' => $data);
}
$data['type'] = 'radio';
return form_checkbox($data, $value, $checked, $extra);
}
Changes with the CI methods
- form_checkbox and form_radio are not checked by default
- form_dropdown needs the multiple attribute if selecting more than one value from the dropdown is needed. This because of the scenario where the user only picks one option.
