php - Update Mysql rows in foreach loop based on selected itemid -


i trying update rows in mysql based on selected checkbox,but query updating rows in table. please check below code:

    if (!empty($_post['checkbox']))      {     // loop store , display values of individual checked checkbox.         foreach ($_post['checkbox'] $selected) {             $sql1="update items set status='1' item_id='$selected'";             $result1=mysql_query($sql1);             if (!$result1)              {                 echo "error while updating";             }             else             {                header("refresh: 2;url=main_menu.php");                mysql_close($conn);                echo "<p>todays menu updated <a href='main_menu.php>click here</a> if     not redirected automatically in 2 seconds<br /></p>";            }         }

here if (!empty($_post['checkbox'])) should use name of checkbox.

for instance, if html below:

  <input type="checkbox" name="checkbox_name" />

you should write if statement below:

if (!empty($_post['checkbox_name']))

the same holds foreach statement , use of in sql statement.

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
