cakePHP formHelper postLink image - php

Question

I want to output an image with a hyperlink wrapped around it instead of just a text hyperlink using cakePHP's formHelper::postLink function.
Does anyone know how to do this? I tried multiple things but couldn't get it working.
<?php echo $this->Form->postLink(
'Delete',
array('action' => 'delete', $country['Country']['id']),
array('confirm' => __('Are you sure you want to delete ').$country['Country']['name'].'?')
)?>
So instead of 'Delete' I want to display an image.

Answer 1

Here's what works for me.
echo $this->Form->postLink(
$this->Html->image('icn_trash.png', array('alt' => __('Effacer'))), //le image
array('action' => 'delete', $artist['Artist']['id']), //le url
array('escape' => false), //le escape
__('Êtes-vous sûr de vouloir effacer artiste #%s?', $artist['Artist']['id']) //le confirm
); //le voila

Answer 2

Try this :
echo $this->Form->postLink(
$this->Html->image('delete.png',
array("alt" => __('Delete'), "title" => __('Delete'))),
array('action' => 'delete', $items['Item']['id']),
array('escape' => false, 'confirm' => __('Are you sure?'))
);

If I understand your question correctly I dont think you want to use $this->Form->postLink
I think this page is exactly what you're after: http://book.cakephp.org/view/1441/image
This uses $this->Html->image to create the image and then you can pass a URL through as one of the parameters to specify the surrounding anchor link.

Answer 4

You can wrap in image inside a link element, but you need to set the escape option to false, like this:
echo $this->Html->link(
$this->Html->image('your_image_here.jpg', array(
'alt' => 'Alternative Text for your image',
'title' => 'Optional tooltip text for your image'
),
array(
'controller' => 'YourController',
'action' => 'someAction'
),
array(
'escape' => false // Add this to avoid Cake from printing the img HTML code instead of the actual image
)
);
That should do the trick.

Answer 5

echo $this->Html->link(
$this->Html->image("recipes/6.jpg", array("alt" => "Brownies")),
array(
'controller' => 'recipes',
'action' => 'view',
'id' => 6,
'comments' => false
)
)

function delete_image(){
if ($this->Session->read('Auth.User.id')) {
$this->User->id = $this->Session->read('Auth.User.id');
$this->User->updateAll(
array('User.image' => "''"),
array('User.id' => $this->User->id)
);
$this->Session->setFlash('The image has been deleted.');
$this->redirect(array('action' => 'profile'));
}
}
