Displaying a message in a dialog box using AJAX, jQuery, and CakePHP
- by LainIwakura
I have a form, and when users submit this form, it should pass the data along to a function using AJAX. Then, the result of that is displayed to the user in a dialog box. I'm using CakePHP (1.3) and jQuery to try and accomplish this but I feel like I'm running into the ground.
The form will eventually be used for uploading images with tags, but for now I just want to see a message pop up in the box..
The form:
<?php
echo $this->Form->create('Image', array('type' => 'file', 'controller' => 'images',
'action' => 'upload', 'method' => 'post'));
echo $this->Form->input('Wallpaper', array('type' => 'file'));
echo $this->Form->input('Tags');
echo $this->Form->end('Upload!');
?>
The AJAX:
$(document).ready(function() {
$("#ImageUploadForm").submit(function() {
$.ajax({
type: "POST", url: "/images/upload/",
data: $(this).serialize(),
async: false,
success: function(html){
$("#dialog-modal").dialog({
$("#dialog-modal").append("<p>"+html+"</p>");
height: 140,
modal: true,
buttons: {
Ok: function() {
$(this).dialog('close');
}
}
})
}
});
return false;
});
});
NOTE: if I put $("#dialog-modal").dialog({ height: 140, modal: true }); OUTSIDE of the $.ajax but inside the $("#ImageUploadForm").submit(function() { and comment out the $.ajax stuff, I WILL see a dialog box pop up and then I have to click it for it to go away. After this, it will not forward to the location /images/upload/
The method that AJAX calls:
public function upload()
{
$this->autoRender = false;
if ($this->RequestHandler->isAjax())
{
echo 'Hi!';
exit();
}
}
$this-RequestHandler-isAjax() seems to do either absolutely nothing, or it is always returning false. I have never entered an if statement with that as the condition.
Thanks for all the help, if you need more information let me know.
