Loading mysql data to a html form and updata with php -


i extremely new both mysql , php (mostly mysql), , i'm not sure got of basics, cause i'm more of learning-by-doing-person. code made of different explanations around web, , of might wrong. i'm trying data database, put html form, edit it, , update database new data. far data gets loaded form correctly, , lot of troubleshooting i've come conclusion upload works out should, except fields empty. guess problem must in getting data form, update query.

this code

<html xmlns="http://www.w3.org/1999/xhtml">  <head> <meta content="text/html; charset=utf-8" http-equiv="content-type" /> <title>untitled 1</title> </head>  <body> <?php require 'connect.php';   $result = $db->query("select * test") or die ($db->error);  while($row = mysqli_fetch_array($result)) {      $name = $row['name'];     $school = $row['school'];     $email = $row['email'];     $grade = $row['grade'];     $workshop = $row['workshop'];     $id = $row['id']; ?> <form method="post" action="#">     <?=$id?>     <input name="nameid" type="text" value="<?=$name?>">     <input name="emailid" type="text" value="<?=$email?>">     <input name="gradeid" type="text" value="<?=$grade?>">     <input name="workshopid" type="text" value="<?=$workshop?>">     <input name="schoolid" type="text" value="<?=$school?>"> <?php }  session_start(); $_session['storage'] = $_post; ?> <input name="update" type="submit" id="update" value="update"> </form>   <?php if(isset($_post['update'])) {      $link = mysqli_connect("localhost", "892847", "123456789", "892847");      // check connection     if($link === false){         die("couldn't connect. " . mysqli_connect_error());     }     session_start();      $name = $_session['storage']['nameid'];     $school = $_session['school']['schoolid'];     $email = $_session['email']['emailid'];     $grade = $_session['grade']['gradeid'];     $workshop = $_session['workshop']['grade'];     $id = $_session['id'];       $sql = "update test set name = '$name', email = '$email', school = '$school', grade = '$grade', workshop = '$workshop' id = '8'";     if(mysqli_query($link, $sql)){         echo "records added successfully. $name";         print_r($_post['nameid']);     } else{         echo "error: not able execute $sql. " . mysqli_error($link);     }       mysqli_close($link); } ?>  </body> </html> 

i'm aware session-chaos looks strange, read somewhere information isn't available across php-scripts, unless make session.

i'm grateful kind of - i've been fighting 48 hours

this basic approach, using easiest procedural php. first, load data in mysql php array follows, assuming you've made connections , id id of specific row

$row = mysql_fetch_array(mysql_query("select * test `id` = '$id'")); 

find way of ensuring that page displaying required id, instance, can use $id = $_get[row]; in case url http://url?row=id in html code use echo follows

<form action="process.php" method="post"> <input type="hidden" name="id" value="<?php echo $_get['row']" ?>" > <input type="text" name="nameid" value="<?php echo $row['nameid'] ?>" > ... </form> 

forget sessions, moment press submit should carry data in process.php in global variable $_post or $_get, depending on method chose in <form method>.

now in process.php, use

$nameid = mysql_real_escape_string($_post['nameid']); $id = $_post['id']; $sql = mysql_query("update test set `name_id` = '$nameid' `id` = '$id'"); if($sql) { echo "update successful"; } 

needless say, need use database connections in both pages.
