I’m working on some cms tool to make posts on site I used a lot of cms like Joomla, WordPress and Textpattern. Now I want to make something like that, of course not even similar to that but just for my personal use and fun.

2 things to do:

1. Option to select all checkboxes. I like something like in joomla in top there is checkbox with titles when u select it all checkbox are selected and if u uncheck it all is unchecked
2. When I press delete button all checkboxes that I select are deleted from database or moved to some other category like trash which is nice because u can in that way return some posts that u delete by mistake or some other reason

Here is my code that bothers me becouse checkboxes don't work

When you're creating your check boxes, you will create a checkbox array, like so:

Code:
&lt;form method="POST"&gt;

&lt;input type="checkbox" name="username[10]" value="Jon Doe" /&gt;

&lt;input type="checkbox" name="username[11]" value="Jane Doe" /&gt;

&lt;/form&gt;

This, being out put dynamically of course. In your database, you would have a table with an "id" field, which represents 10 and 11 in the above example.

When you click both of these buttons, and then click a "delete" button, this will post an associative array that will look like this:

Code:
array

      10 => string 'Jon Doe' (length=7)

      11 => string 'Jane Doe' (length=8)

Now you run a delete sql command inside a "foreach" loop that will remove the entry with that ID number.

This is quick and dirty...someone else may have a better suggestion, and I - for one - would definitely like to hear it, because I'm always looking for new ways to deal with checkboxes and radio buttons

@robison....

That's a mess of a code...and the reason why CodeIgniter exists....to avoid procedural jumbled up code like you've posted. Are you attempting to switch all of that over to CodeIgniter?
