I have checkboxes in my HTML form and i want to delete several records from my database using those checkboxes. I'm quite new to php so I have a dificulty in manipulating the checkboxes. so can anyone help me? thank you!
Example....
I have 5 records and i want to delete two. So i'll check 2 checkboxes and then "submit" it. how do i do this in php? making sure that the records were really deleted in my database.
Jump to Post<input type='checkbox' name='someArray[]' value='1' /> <input type='checkbox' name='someArray[]' value='2' /> <input type='checkbox' name='someArray[]' value='3' />Then in PHP
$someArray = $_REQUEST['someArray']; foreach($someArray as $key=>$someElem){ $query = "DELETE FROM someTable WHERE id = ".$someElem; }
<input type='checkbox' name='someArray[]' value='1' />
<input type='checkbox' name='someArray[]' value='2' />
<input type='checkbox' name='someArray[]' value='3' />Then in PHP
$someArray = $_REQUEST['someArray'];
foreach($someArray as $key=>$someElem){
$query = "DELETE FROM someTable WHERE id = ".$someElem;
}I think something's wrong with this code that i made.....the 1st part is the FORM part, the 2nd part is the PHP part

Assuming that you have the checkboxes named as deletethis[] where the indexes are the indexes in the table, on submitting the form with check box include a code like this. DeleteFunction is a function which deletes the row with id from a specific table.
$chk=$_POST['deletethis'];
$iserror=false;
for($i=0;$i<count($_POST['deletethis']);$i++){
$result=DeleteFunction(key($chk));
if(!is_numeric($result)){
$iserror=true;
break;
}
next($chk);
}if u having any problems ask
Just a tip:
If you are going to use the checkboxes on each record, you cannot use another form with in that table.
Start the <form> at the top and insert a checkbox on each row... then add a submit button at the to and/or bottom of the table and close that form.
