Similar TutorialsHello everyone, I am attempting to delete a row from my SQL database. I'm using phpMyAdmin for my database manager. I've tried to do this two different ways (which are posted below), but each way is initiated by selecting a delete button on the previous page. I'm not getting any errors, and it is running through and displaying the "Success!" line, but not deleting anything. Thanks in advance for any help. Attempt #1: $max = mysql_query("SELECT MAX(ART_ID) AS maxAID FROM Artisan"); $numrows = mysql_num_rows($max); if($numrows == 0) { echo "Artisan was not deleted."; ?> ---some html filler that doesn't use the php above or below---- <?php } else { while (mysql_fetch_array($max)) { $ART_ID = $row['maxAID']; $deleteArtisan = mysql_query ("DELETE FROM Artisan WHERE ART_ID = '$ART_ID'"); $deleteAnswers = mysql_query ("DELETE FROM ArtisanAnswer WHERE ART_ID = '$ART_ID'"); echo "success!"; if (!$deleteArtisan || !$deleteAnswers) { die ("error: " .mysql_error()); } } } Attempt #2: $id = $_REQUEST['ART_ID']; $max = mysql_query("SELECT * FROM Artisan WHERE ART_ID = '$id'"); while(mysql_fetch_row($max)) { $deleteArtisan = mysql_query ("DELETE FROM Artisan WHERE ART_ID = '$ART_ID'"); $deleteAnswers = mysql_query ("DELETE FROM ArtisanAnswer WHERE ART_ID = '$ART_ID'"); echo "success!"; if (!$deleteArtisan || !$deleteAnswers) { die ("error: " .mysql_error()); } } Hi, I dont know what doing wrong Code: [Select] <form ... <?php if($_POST['DeleteActor']) { mysql_query( 'DELETE FROM `n_dramaact` WHERE `n_dramaact_id` = "' . $_POST['n_dramaact_id'] .

I wish to improve my coding base. Basically when you fill out the register form, it will check for data, then execute the insert query.

I am having trouble getting the delete function to work. I pick the user that I want to remove from the system. I verify that this is the right person to remove.

Any help or solutions would be much appreciated... I want to delete a file, I'm using Windows XP, however, it gives me Permission Denied: Code: [Select] $file =$row['img'] ; $filedel = "mages/".$file; unlink ($filedel); Is the code wrong? I tried setting permission to the folder but in vain... Not sure how to go about making it so that I can delete and edit a post.. So I am stumped on how to make it to delete and edit post. The key factor for getting the information is the id field. And I am able to get it and display it, but how can I get it to work between all my functions? This is what I have so far. <?php include 'test.php'; function connection() { $connection = @mysql_connect('localhost','root','') or die('could not connect to mysql'); $select_db = @mysql_select_db('tutorials') or die('could not connect to database'); } function delete_post($id) { connection(); $query = "DELETE FROM `posts` WHERE `id` = '$id'"; $result = mysql_query($query); } function find_posts() { connection(); $query = 'SELECT `posts`.`title`, `posts`.`body`, `posts`.`id`, `users`.`username` FROM `posts`, `users` WHERE `posts`.`user_id` = `users`.`id`'; $result = mysql_query($query); while ($row = mysql_fetch_array($result)) { $id = $row['id']; echo '<b>' . $row['title'] . '</b>' .'<a href=/practice/model/posts.php?action=delete>[delete]</a> <a href=/practice/model/posts.php?action=edit>[edit]</a>' . '<br/>'; echo $row['body'] . '<br/>'; echo $row['username'] . '<p>'; } } function find_post($id) { connection(); $query = "SELECT `posts`.`title`, `posts`.`body`, `posts`.`id`, `users`.`username` FROM `posts`, `users` WHERE `posts`.`user_id` = `users`.`id` AND `posts`.`id` = '$id'"; $result = mysql_query($query); $row = mysql_fetch_array($result); echo '<b>' . $row['title'] .

'<p>'; } function create_post() { connection(); $title = $_POST['title']; $body = $_POST['body']; $query = "INSERT INTO `posts` SET `title` = '$title', `body` = '$body', `created_at` = NOW(), `user_id` = 53"; $result = mysql_query($query); if(!$result) { echo mysql_error(); } } delete_post(7); find_posts(); ?> <?php $action = $_GET['action']; switch ($action) { case 'create': echo 'created' .

Sorry for the vague description, but its kind of hard to put it into words. If you need a more detailed description please let me know and I will try to. Pretty much want to be able to delete and edit my posts. Thank you! I can't seem to figure this out. The queries seem to need to be in the foreach loop. The queries will then work but they update every blog post in my table. I only want it to update the 1 that has the button associated with it. So for instance... only delete the blog post where post_id = ${post['id']} Do I make the queries be outside of the foreach? If I do that then MySQL fails because my foreach is using the $post variable. Code: [Select] <?php if (isset($_POST['approve'])) { $sql = " UPDATE `blog_posts` SET `approved` = 1 WHERE `post_id` = '${post['id']}' "; mysql_query($sql) or die(mysql_error()); } else if (isset($_POST['deny'])) { $sql = " UPDATE `blog_posts` SET `approved` = -1 WHERE `post_id` = '${post['id']}' "; } else if (isset($_POST['delete'])) { mysql_query("DELETE FROM `blog_posts` WHERE `post_id` = {$post['id']}") or die(mysql_error()); } foreach ($posts as $post) { ?> <div class="post" id="post<?php echo $post['id']; ?>"> <form action="blog.php" method="post" id="blogform" class="man"> <fieldset class="mvs buttonfield"> <span class="button"> <label> <input type="submit" id="starttop" name="approve" class="invis dark_grey" value="Approve" /> </label> </span> <span id="smarktop" class="button disabled"> <label> <input type="button" id="marktop" name="deny" class="invis dark_grey" value="Deny" disabled="disabled" /> </label> </span> <span id="sdeletetop" class="button disabled"> <label> <input type="submit" id="deletetop" name="delete" class="invis dark_grey" value="Delete" disabled="disabled" /> </label> </span> </fieldset> </form> </div> <?php } ?> i need help trying to get this delete feature to work its not deleting from the database (by the way i took out my database names and passwords at the top of the file) is it possible someone could help me, ive been working on this for like a week and cant figure out the problem. thanks! you can email me at spr_spng@yahoo.com picture 2.png is showing what it looks like Code: [Select] <?php $host="localhost"; // Host name $username="username"; // Mysql username $password="password"; // Mysql password $db_name="database_name"; // Database name $tbl_name="table_name"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $count=mysql_num_rows($result); ?> <style> /*table affects look of the whole table look */ table { margin-left: auto; margin-right: auto; border: 1px solid #330000; border-collapse:collapse; width:70%; border-width: 5px 5px 5px 5px; border-spacing: 1px; border-style: outset outset outset outset; border-color: #330000 #330000 #330000 #330000; border-collapse: separate; background-color: #330000; #800517 f535aa #330000 school color #9A0000 school color2 #991B1E school color3 #CCCC99 school color4 #9A0000 } /*th is table header */ th { text-align: left; height: 2.5em; background-color: #330000; color: #FC0; font-size:1.5em; } /*td is table data or the cells below the header*/ td { text-align: left; height:1.0em; font-size:1.0em; vertical-align:bottom; padding:10px; border-width: 5px 5px 5px 5px; padding: 8px 8px 8px 8px; border-style: outset outset outset outset; border-color: #9A0000 #9A0000 #9A0000 #9A0000; background-color: #CCCC99; -moz-border-radius: 0px 0px 0px 0px; } </style> <table width="400" border="0" cellspacing="1" cellpadding="0"> <tr> <td><form name="form1" method="post" action=""> <table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC"> <tr> <td bgcolor="#FFFFFF"> </td> <td colspan="4" bgcolor="#FFFFFF"><strong>Pick Which Rows you want to delete, Then press delete.</strong> </td> </tr> <tr> <td align="center" bgcolor="#FFFFFF"><strong>Id</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Name</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Lastname</strong></td> <td align="center" bgcolor="#FFFFFF"><strong>Email</strong></td> <td align="center" bgcolor="#FFFFFF">delete</td></tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td bgcolor="#FFFFFF"><? echo $rows['id']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['name']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['lastname']; ?></td> <td bgcolor="#FFFFFF"><? echo $rows['email']; ?></td> <td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td> </tr> <?php } ?> <tr> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td> </tr> <? // Check if delete button active, start this // edited if($delete){ for($i=0;$i<$count;$i++){ $del_id = $checkbox[$i]; $sql = "DELETE FROM $tbl_name WHERE id='$del_id'"; $result = mysql_query($sql); } // if successful redirect to delete_multiple.php if($result){ echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">"; } } mysql_close(); ?> </table> </form> </td> </tr> </table> Can someone help me understand exactly how queries work in PHP?

I've got this mess of a page I'm trying to manipulate to add a feature to. When somebody goes to this page, it pulls all records. At the top, I added a way to refine the results by dates. That query works fine, I tested it in mysql. To avoid fighting with the original code, I created an if statement to create $query_selectAll. But when I put it in the page, it would just refresh with the same data. I echoed the query to make sure it is correct. Then I realized that there was another query, $query_selectAllItems, further down the page that was generating the results, and none of what I was doing made a difference. But I'm not sure why it's ignoring my query or how to work around this. I tried deleting the query $query_selectAllItems, thinking it would take mine, because it ends with the same: $result_all $result_all = mysql_query($query_selectall); or $result_all = mysql_query($query_selectAllItems); Code: [Select] <?php require_once('calendar/classes/tc_calendar.php'); include("include/auth.php"); include("include/conn.php"); @$a_row = mysql_fetch_array($result); // I added this if statement in to get my POST results, without having to make changes to the GET results he made. if (isset($_POST['view'])){ $view=$_POST['view']; } else { $view=$_GET['view']; } if ($view=="All") { $query_selectall = 'select * from tbl_registration'; echo $query_selectall; } elseif ($view=="dated") { $mydate = isset($_REQUEST["date5"]) ?

Been trying to run a query to get all rows from a table between two dates, but nothing seems to work.
$query = "SELECT * FROM table WHERE date BETWEEN '%2014-11-17%' AND '%2014-11-18%'";
Strange thing if I try a search instead a query in phpmyadmin I don't see an operator called 'BETWEEN' on the remote host, but I do on my localhost.
Does this mean it will never work on the remote host? Nevertheless it doesn't work on either and I do have records for both dates in the table.
phpmyadmin:
Version 4.1.14 localhost (wamp) Version 3.3.7deb7 on remote server Thanks Hey, $todo_upgrades_sql = "SELECT * FROM todo_upgrades WHERE time_completion >= $time"; $todo_upgrades_res = mysql_query($todo_upgrades_sql) or die (mysql_error()); results: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 Hi all, Perhaps, let me briefly explain what I would like to achieve. Currently I am using INNER JOIN command to link 4 sql tables 1) tutor_overall_level_subject.sql 2) tutor_subject_level.sql 3) tutor_level.sql 4) tutor_subject.sql In tutor_level.sql, there are 11 'level_id' level id 1 == Pre-School level id 2 == Lower Primary School level id 3 == Upper Primary School level id 4 == Lower Secondary etc.... As you can see from the code below, I am trying to retrieve 'lower primary' records only and place it in a table Subsequently, 'upper primary' records and place it in another table However when I executed the code, I receive a blank page. What could have gone wrong? Thanks if ($row3['level_id'] == 2){} if ($row3['level_id'] == 3){} Code: [Select] <?php //Retrieve Lower Primary if ($row3['level_id'] == 2) { echo'<table><tr>'; echo '<td class="label">Lower Primary</td>'; $count = 0; while($row3 = mysqli_fetch_array($data3)) { if ($count % 5 == 0) { echo "</tr><tr>"; $count = 0; } echo '<td>' . $row3['subject_name'] . '</td>'; $count++; } echo '</tr></table><br/>'; } //Upper Lower Primary if ($row3['level_id'] == 3) { echo'<table><tr>'; echo '<td class="label">Upper Primary</td>'; $count = 0; while($row3 = mysqli_fetch_array($data3)) { if ($count % 5 == 0) { echo "</tr><tr>"; $count = 0; } echo '<td>' . $row3['subject_name'] .
