[FIXED] Why we use escape => false in cakephp

Issue

echo $this->Html->link(
    '<span class="glyphicon glyphicon-remove"></span> Cancel',    
    array(
        'action'=>'index', 
        'page:'.$this->request->data['Transaction']['page']
    ),
    array(
        'class'=>'btn btn-default', 
        'escape'=>false
    ), 
    'Do you want to cancel ?'
);

Solution

Because your label is HTML rather than plain text.

You don't want to insert a literal <span class="glyphicon glyphicon-remove"></span> text, you want an HTML tag to display an icon.

    // lib/Cake/View/Helper/HtmlHelper.php
    if (isset($options['escapeTitle'])) {
        $escapeTitle = $options['escapeTitle'];
        unset($options['escapeTitle']);
    } elseif (isset($options['escape'])) {
        $escapeTitle = $options['escape'];
    }

    if ($escapeTitle === true) {
        $title = h($title);
    } elseif (is_string($escapeTitle)) {
        $title = htmlentities($title, ENT_QUOTES, $escapeTitle);
    }
