拆分AJAX POST变量

Question

I have written a script to post AJAX variables whenever a checkbox is clicked. When multiple checkboxes are selected the variables are stored in an array and seperated by a pipe . I need each variable to be passed separately into my php function so I can run separate queries.

My JavaScript

$(document).on("change", ".tbl_list", function () {
    var tbls = new Array();
    $("input:checkbox[name='tbl[]']:checked").each(function () {
        tbls.push($(this).val());
    });
    var tbl = tbls.join('|');
    var db = window.sessionStorage.getItem("db");
    alert(db);
    $.ajax({
        type: "POST",
        url: "ajax2.php",
        data: {
            tbl: tbl,
            db: db
        },
        success: function (html) {
            console.log(html);
            $("#tblField").html(html).show();
        }
    });
});

Output when multiple tables are selected

tbl:db|event

My PHP function

function tblProperties() {
    if (isset ( $_POST ['tbl'] )) {
        $tbl = $_POST ['tbl'];
        $db = $_POST ['db'];
        $link = mysqli_connect ( 'localhost', 'root', '', $db );
        $qry = "DESCRIBE $tbl";
        $result = mysqli_query ( $link, $qry );

I know I would need to store these variables somehow and then do a for each to generate separate queries but i'm not sure how to do it.

Answer 1

Do this:

function tblProperties() {
    if (isset ( $_POST ['tbl'] )) {
        $db = $_POST ['db'];
        $tables = explode('|', $_POST ['tbl']); // explode your variable
        $link = mysqli_connect ( 'localhost', 'root', '', $db );

        foreach($tables as $table) // foreach through it
        {
            $result = mysqli_query ( $link, "DESCRIBE $table" ); // do your query
            while($row = mysqli_fetch_array($result))
            {
                // your code here 
            }
        }
}

use this,

function tblProperties() {
    if (isset ( $_POST ['tbl'] )) {
        $tbl = $_POST ['tbl'];
        $db = $_POST ['db'];
        $link = mysqli_connect ( 'localhost', 'root', '', $db );
     $tblarr =  explode('|', $tbl);
     for($i = 0 ; $i < sizeof($tblarr); $i++)
    {
         $qry = "DESCRIBE $tblarr[$i]";
        $result[] = mysqli_query ( $link, $qry );
     }
