In Php as we all know, there are no inbuilt controls by itself like Asp.Net's GridView etc. I am using Html's <table>
to build up the grid and keep the row's id in one hidden field. I've also placed one checkbox at the beginning of each row and a delete button at the bottom of the grid. The problem i face is, how do i get all the id's that are checked so that i can pass those ids in my IN
clause of Delete
?

First you name all your checkboxes by suffixing
[]
in their name so that an array gets created, later this is how you can get those that are checked and act accordingly:for($i = 0; $i < count($_POST['checks']); $i++) { if (isset($_POST['checks'][$i])) { // this was checked !! } }
Where
checks
is the name of all those checkboxes eg:<input type="checkbox" name="checks[]" value="1" /> <input type="checkbox" name="checks[]" value="2" /> <input type="checkbox" name="checks[]" value="3" />
And this is how you can get those for your
IN
clause in your query:$checked_array = array(); for($i = 0; $i < count($_POST['checks']); $i++) { if (isset($_POST['checks'][$i])) { $checked_array[] = mysql_real_escape_string($_POST['checks'][$i]); } } // build comma separated string out of the array $values = implode(',', $checked_array);
Now you can use the
$values
in yourIN
clause of your query.本回答被题主选为最佳回答 , 对您是否有帮助呢?解决 无用评论 打赏 举报
