A common practice that some users have is to press the enter key when they are filling in forms on the web. This might be when they are just moving to the next field, but the trouble is that this will submit the form.

To prevent this from happening you can simply stop the form being submitted if the enter key had been pressed. This is done by binding a JQuery event to the input elements of the form and returning false if the key pressed is enter, which has the keyCode value of 13. We also include a call to the JQuery method preventDefault() to stop the event propagating.

One new feature of Drupal 7 is that any title you give a node will be copied to the menu title field when you create a menu item. I wanted to replicate this functionality in Drupal 6 and so I created a function that did just that. I have used this function a few times in different projects so I'm posting it here.

iFrames can be a convinent way of loading content from one domain onto another, but they do have their limitations. For example, it usually isn't possible to style the contents of the iFrame and you are therefore left at the mercy of a third party site. They also look pretty shonky if the third party site does down for whatever reason. Displaying large "page not found" statements on your page is quite unsightly.

The other day I was trying to convert a HTML template into a CMS system and I found a stumbling block with the use of the jQuery function delay() in the template's JavaScript. During part of the templating process I found the following error occurring on the page.

Whilst creating a small plugin on a Wordpress site I decided not to use the media library as I just wanted to add some small stub images to the content. I created some boxes on the post page using add_meta_box() and added a file input box to them. The only thing is that the post form in Wordpress doesn't have the enctype="multipart/form-data" attribute and so it won't pass file to the $_FILES array in PHP.

It is not possible to add the enctype into the form declaration via Wordpress as there is no hook or action to do this. So the only alternative (rather than hack the source code) is to add the attribute using JavaScript, and as we have JQuery already loaded we can utilise that.

Opening external links in a new window can be useful, but adding target="_blank" can be a real chore. Not only that, but if you are trying to validate the page to XHTML strict then the target attribute will cause errors to appear as it is not defined in XHTML.
