I’m trying to create a page where I input a MYSQL query: SELECT column1,column2

  • 0

I’m trying to create a page where I input a MYSQL query: SELECT column1,column2 FROM table;, and dynamically create an HTML table with column titles.

EDIT: removed most of my question, just left the question part. I have since created a script that does this and included it as an answer. I hope someone else makes use of it like I do (when I’m too lazy to log into phpmyadmin … hahaha).

    Well. Here’s how I accomplished this, building on webjprgm’s tip to use mysql_fetch_assoc:

    php code to dynamically create a table with column titles, from PHP to mysql to html! :)

<?php

    /* posted data sent to this page (from this page)*/

    $pdatabase      = htmlentities($_POST['database'],  ENT_QUOTES);    // database
    $phost          = htmlentities($_POST['host'],      ENT_QUOTES);    // host
    $puser          = htmlentities($_POST['user'],      ENT_QUOTES);    // user
    $ppassword      = htmlentities($_POST['password'],  ENT_QUOTES);    // password

    $pcolumns       = htmlentities($_POST['columns'],   ENT_QUOTES);    // comma seperated columns
    $columns        = explode(",",$pcolumns);                           // array of column names

    $ptable         = htmlentities($_POST['table'],     ENT_QUOTES);    // table
    $pwhere         = str_replace(array(";",'"'),array('',''),$_POST['where']);    // WHERE clause
    if (!empty($pwhere)) {$pwhere = "WHERE $pwhere";}                   // if not empty, prepend with "WHERE"

    $porder         = htmlentities($_POST['order'],     ENT_QUOTES);    // ORDER BY clause
    $psort          = htmlentities($_POST['sort'],      ENT_QUOTES);    // SORTING (asc or desc)
    if (!empty($porder)) {$porder = "ORDER BY $porder $psort";}         // if order is not empty, prepend with "ORDER BY"

    $pgroup         = htmlentities($_POST['group'],     ENT_QUOTES);    // GROUP BY clause
    if (!empty($pgroup)) {$pgroup = "GROUP BY $pgroup";}                // if not empty, prepend with "GROUP BY"

    $plimit         = htmlentities($_POST['limit'],     ENT_QUOTES);    // LIMIT clause
    if (!empty($plimit)) {$plimit = "LIMIT $plimit";}

    /* The finished product....or query...so to speak...if you will */
    $query          = "SELECT $pcolumns FROM $ptable $pwhere $pgroup $porder $plimit";

    /* Safety precautions */
    $query          = str_replace(array("delete","drop","update","alter"),array('','','',''),$query);


    // print_r($columns);
