Add html element inside of form element using cake php form helper

问题

I am trying to create a simple html output that looks like this

<button class="searchbutton" id="search_button" type="submit">-->
      <i class="icon-search"></i> Search</button>

with Cake php's form helper, i cant figure out why the 'after' attribute doesn't add the inner <i> </i> html element.

This is what i have tried.

  echo $this->Form->button('Search', array('type' => 'submit','id' => 'search_button','class' => 'searchbutton',
        'after' => "<i class='icon-search'></i>"));

回答1:

You just include the extra <i></i> tag in the button $title, also include 'escape' => false to ensure the mark up is not escaped, even though is not escaped by default as on v3.1.1, this may change in future, who knows..

Example:

echo $this->Form->button("<i class='icon-search'></i> Search", array('type' => 'submit','id' => 'search_button', 'class' => 'searchbutton', 'escape' => false));

Please try below code.

echo $this->Form->button('Search', array('type' => 'submit','id' => 'search_button','class' => 'searchbutton','escape' => true,
        'after' => "<i class='icon-search'></i>"));
