how to pass a value to php variable by ajax

Question

this is my javascript code :

function  category(row){
    dataparam = \"oper=delete&row=\"+row;
    $.ajax({
        type: \"POST\",
        url: \"multiuplo         


        

Answer 1

It looks like you have this wrong, $_REQUEST['opers'] it should be $_REQUEST['oper']

$opers = (isset($_REQUEST['oper']) and $_REQUEST['oper'] != '' ) ? $_REQUEST['oper'] : '';  

if($opers == "delete") {
    $row=$_REQUEST['row'];
    echo $row;
}

I would also recommend that as you are expecting the values to come via URL you use the appropriate super global which is $_GET. There is a very small chance that a $_COOKIE could screw you over. If you use them and hapen to give it the value of 'oper'.

Answer 2

In your dataparam variable you have "oper=delete&row="+row; and in the PHP code you test for $_REQUEST['opers']), since oper <> opers, the failure is perfectly normal, just add or remove the s somewhere.

Answer 3

You want $_REQUEST['opers'] while you pass oper. Notice the additional "s".

Answer 4

$opers = (isset($_REQUEST['oper']) and $_REQUEST['oper'] != '' ) ? $_REQUEST['oper'] : '';  
if($opers == "delete")
{
     $row=$_REQUEST['row'];
     echo $row;
}

Hopefully the problem is with the extra curly brackets. Check it. I have corrected the code. Let me know if it works. And there is an extra s in opers.
