I want on the code following delete one or few rows (multiple rows) in the mysql, But unfortunately dont work,testing on the server and localhost but dont work.i want just use css and div, dont use tabel,i want act on the local and the server,please help me.
[LIST=1]
[]The meta tag will not work outside the head element on an HTML document, so that method is out.
[]Your loop will only validate if the last delete statement worked, not all of them
[]You can use the header instruction instead, but you’ll need to reorder the code to accomplish what you want.
[]A non-php word of advice - avoid inline styles as much as possible. You’ll save yourself a lot of headaches. You can use multiple classes for the same element, just separating them by a space…
[*]The generated page will not validate because you’ve got form elements (the checkboxes) outside the form itself, so results can get sketchy…
[/LIST]This should get you what you need. If not, ensure that your ID is actually a character field - if not, remove the quotes around $del_id in the delete statement.

grr… Trying to do too many things in too many languages today
What’s happening is that line (which is the only php was to do a response.write) expects to be the first thing sent, so all the base html stuff at the top of the page is killing it. Take all of the html from the first line down and including the body tag and move it to right above the div class=“container” line (after the php closing tag).
Crap - was doing too much at one time and I missed an obvious problem…
Change the code to this and you should be OK. StarLion was correct - the checkboxes need to be inside the form (which I thought I had fixed - obviously not…)

Not to mention that the definition in line 48 means nothing for the loop in line 17. You want the number of $checkbox elements there. count($checkbox) , or a foreach.
