  1. I have a simple user login where it inserts the user session into database like this (id, user_id, hash). It works fine. I can delete the session from the database when the user logs out. Now I realized something. When I close the browser window, it'll destroy the session(log out the user) as intended but it won't delete the session from the database. I was wondering if there is a way to do that?
  2. Ok this is puzzleing. I am geting "Could not delete data: 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 '1' at line 1". but its is deleting the entry that needs to be removed. The "1" is the entry. Just not sure what is causing the error. I do have another delete php but I have put that on the back burning for the time being. <?php $con = mysqli_connect("localhost","user","password","part_inventory"); // Check connection if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } else { $result = mysqli_query($con, "SELECT * FROM amp20 "); $amp20ptid = $_POST['amp20ptid']; // escape variables for security $amp20ptid = mysqli_real_escape_string($con, $_POST['amp20ptid']); mysqli_query($con, "DELETE FROM amp20 WHERE amp20ptid = '$amp20ptid'"); if (!mysqli_query($con, $amp20ptid)); { die('Could not delete data: ' . mysqli_error($con)); } echo "Part has been deleted to the database!!!\n"; mysqli_close($con); } ?>
  3. All I want to do is simply delete a record/row using ajax. For the life of me, I can't get it to work. I have tried many different methods and played around with them. Here is a basic example. Please do tell me what's wrong with it and how I can fix it. index.php <html> <head> <title>Home page</title> <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script> <script> $(document).ready(function() { $(function() { $(".del-action").click(function() { var commentContainer = $(this).parent(); var id = $(this).attr("id"); var string = 'id='+ id ; $.ajax({ type: "GET", url: "delete.php", data: string, cache: false, }); }); </script> </head> <body> <?php $get = DB::getInstance()->query("SELECT * FROM records WHERE record_id = 28 "); if(!$get->count()) { echo 'no record found!'; } else { foreach($get->results() as $row) { $record_id = $row->record_id; ?> <div class="record"> <a href="#" class="del-action" id="<?php echo $record_id; ?>" >Delete</a> </div> <?php } } ?> </body> </html> delete.php $record_id = intval($_GET['id']); $delete = DB::getInstance()->delete('records', array('record_id', '=', $record_id)); ps. it deletes the records fine without ajax/js. I just need help with the js code so that I can delete the record without redirecting or refreshing the page.

    Delete All Messages Button

    Hey guys just wandered if you can help me on my website in the mailbox section next to the message there is a delete button to obviously delete that current message. However as I am sure you can appreciate it get tedious when you have 20 messages to do them all at once. So I am after putting a button at the top of this column in the table that will delete all the messages in there with one click. Below is the coding of where all this takes place: function mailbox($mes,$page) { global $config; if(!$page) { $page="1"; } $page=($page - 1); $totalmes=mysql_query("SELECT COUNT(*) FROM messages WHERE toid='".$_SESSION['tid']."' AND rcvddel=0"); $totalmes=mysql_result($totalmes,0); $out[body].=" <div style='float:left;width:69%;margin:5px;'> <table cellspacing='1' cellpadding='1' border='0' width='100%'> <tr> <td width='100%' class='blk_tcon' colspan='5'><b>" . LANG_MAI_MAILBOX . "</b></td> </tr> <tr> <td width='50%' colspan='2' class='blk_tcon_top'>" . LANG_MAI_SUBJECT . "</td> <td width='20%' class='blk_tcon_top'>" . LANG_MAI_FROM . "</td> <td width='25%' class='blk_tcon_top'>" . LANG_MAI_DATE . "</td> <td width='5%' class='blk_tcon_top'></td> </tr>"; $fmail=mysql_query("SELECT id,fromid,subject,active,sent FROM messages WHERE toid='".$_SESSION['tid']."' AND grid='1' AND rcvddel=0 ORDER BY sent DESC LIMIT $page, 15"); while(list($id,$fromid,$subject,$active,$sent)=mysql_fetch_row($fmail)) { $from=mysql_query("SELECT name FROM members WHERE id='$fromid'"); $from=mysql_fetch_array($from); if($fromid == '01') { $froma="Site Challenge"; }else{ $froma="<a href='./profile.php?account=$fromid'>$from[name]</a>"; } if($active == 1) { $icon="<img src='./images/unread.gif' border='0' alt='' />"; $title="<a href='./mailbox.php?action=readmail&mailtype=received&mid=$id'><b>$subject</b></a>"; }else if($active == 2){ $icon="<img src='./images/read.gif' border='0' alt='' />"; $title="<a href='./mailbox.php?action=readmail&mailtype=received&mid=$id'>$subject</a>"; }else{ $icon="<img src='./images/replied.gif' border='0' alt='' />"; $title="<a href='./mailbox.php?action=readmail&mailtype=received&mid=$id'>$subject</a>"; } $out[body].=" <tr> <td width='5%' align='center' class='blk_tcon'>$icon</td> <td width='45%' align='left' class='blk_tcon'>$title</td> <td width='20%' align='center' class='blk_tcon'>$froma</td> <td width='25%' align='center' class='blk_tcon'>$sent</td> <td width='5%' align='center' class='blk_tcon'> <form method='post'> <input type='hidden' name='mail[id]' value='$id' /> <input type='hidden' name='mail[mailtype]' value='received' /> <input type='hidden' name='action' value='delete' /> <input type='submit' class='button' name='submit' value='X' style='color:red; font-weight:bold;' title='" . LANG_MAI_DELETE . "' /> </form> </td> </tr>"; } if($totalmes == 0) { $out[body].=" <tr> <td width='100%' align='center' colspan='5' class='blk_tcon'>" . LANG_MAI_MAILBOX_EMPTY . "</td> </tr>"; } $pagenow=($page + 1); $pages=1; if($pagenow==1) { $skipranks.="[$pages] "; }else{ $skipranks.="<a href='./mailbox.php?page=1'>$pages</a> "; } $arank=1; $brank=15; while($brank < $totalmes) { $arank=($arank + 15); $brank=($brank + 15); $pages++; if($pagenow==$arank) { $skipranks.="[$pages] "; }else{ $skipranks.="<a href='./mailbox.php?page=$arank'>$pages</a> "; } } $out[body].=" <tr> <td width='100%' align='center' class='blk_tcon' colspan='5'>$skipranks</td> </tr> </table> </div> ".TOP_MENU.""; include("$config[html]"); } </tr>"; That is the whole coding of the mailbox received section, as you can see the messages section is all done in form coding so can i pop a nice button at the top to delete all or does it have to be check boxes and stuff. For help with the view of this I have attached a screenshot Thanks for any help in advance.

    Search and Delete

    Hello PHP friends, With the help of 2 members here, namely Guru and Clarkey i manage to finalize the Search and this is part of the search.php codes. { $student_id = $row['student_id']; $searchResults .= "<tr>\n"; $searchResults .= " <td>{$row['LRN']}</td>\n"; $searchResults .= " <td>{$row['first_name']}</td>\n"; $searchResults .= " <td>{$row['last_name']}</td>\n"; $searchResults .= " <td>{$row['grade']}</td>\n"; $searchResults .= " <td>{$row['section']}</td>\n"; $searchResults .= " <td><a href='View_Profile.php?id={$student_id}'>View</a> </td>\n"; $searchResults .= " <td><a href='Admin_Edit_Student_Info.php?id={$student_id}'>Update</a></td>\n"; $searchResults .= " <td><a href='Delete.php?id={$student_id}'>Delete</a></td>\n"; $searchResults .= "</tr>\n"; } As we can see we have 3 target links here the VIEW/UPDATE/DELETE. My concern today is to create the Delete.php which if we are going to click the delete. The student selected will be deleted from the database. Thank you very much for reading. Please comment and never hesitate to give suggestions. By the way this is my present codes in connection, please comment and suggest here. //Connect to MySQL Server include 'Connect.php'; mysql_connect($host, $dbusername, $dbpassword); //Select Database mysql_select_db($dbname) or die(mysql_error()); // Escape User Input to help prevent SQL Injection $first_name = mysql_real_escape_string(trim($_GET['first_name'])); // Retrieve data from Query $query = "SELECT * FROM student_information WHERE first_name LIKE '%{$first_name}%'"; $result = mysql_query($query) or die(mysql_error()); :-)
  7. I have 2 issues happening, first one I need to get resolved is, line 60 is giving me a 'Notice: Undefined variable: delete'.

If you need any other info please let me know, Again I am new at this. <tr> <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete value="delete"></td> </tr> <?php // Check if delete button active, start this *line 60* -----> if ($delete){ for($i=0;$i<$count;$i++){ $del_id = $checkbox[$i]; $sql = "DELETE FROM $tbl_name WHERE id='$del_id'"; $result = mysqli_query($sql); } // if successful redirect to delete_multiple.php if($result){ echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">"; } } mysqli_close($con); ?>
  8. Hey guys! Fairly new with PHP/MySQL and been working on a website for a class, and having some issues with my drop down not working as intended. What I'm trying to do is simply allow the user to select a name from a drop down field, then after pressing the submit button, would delete the selected name from the database. Here is my code. <?php ini_set('display_errors', 'on'); error_reporting(E_ALL); session_start(); $_SESSION['title'] = "PEC Menu"; //Opening Session Vars $currentFile = $_SERVER["PHP_SELF"]; //current page for menu $currentUser = $_SESSION['currentname']; // users account info include('../../functions/mainmenu.php'); // menu functions //Menu Content,Code / Buttons Goes here DrawMenu($currentFile, $currentUser); //Setting up database mysql_connect("localhost","root","changeme"); mysql_select_db("certestdb"); $dbLink = mysql_connect("localhost", "root", "changeme"); mysql_query("SET character_set_client=utf8", $dbLink); mysql_query("SET character_set_connection=utf8", $dbLink); $result = mysql_query("SELECT distinct TermID FROM clinical") or die(mysql_error()); $result2 = mysql_query("SELECT FullName FROM useraccess") or die(mysql_error()); $options=''; $options2=''; while($row=mysql_fetch_array($result)) { if (isset($_POST)) { $TermID=$row["TermID"]; $options.= '<option value="'.$row['TermID'].'">'.$row['TermID'].'</option>'; } }; while($row=mysql_fetch_array($result2)) { if (isset($_POST)) { $FullName=$row["FullName"]; $options2.= '<option value="'.$row['FullName'].'">'.$row['FullName'].'</option>'; } }; if (isset($_POST)) { mysql_query("DELETE FROM useraccess WHERE FullName='$FullName'") or die(mysql_error()); echo "Success!"; } else { echo "Not successful"; } ?> <html> <style> </style> <body> <h4> Add User</h4> <form name = "AddUser" action="PEC_addUser.php" method= "get" style = "text-align:right; color: Black;float:left;"> <input type="submit" value="Add User"> </form><br><br> <hr size = "5" color = "darkgray"> <h4> Assign User to Course</h4> <form name = "AssignUser" action=" " method= "get" style = "text-align:right; float:left; color: darkred;"> User: <select> </select> Course: <select> </select> Term: <SELECT NAME= termid> <OPTION VALUE=0>Choose</OPTION> <?php echo $options; ?> </select> <input type="submit" value="Assign"> </form> <br><br> <hr size = "5" color = "darkgray"> <h4> Assign Student to Instructor </h4> <form name = "AssignStudent" action=" " method= "get" style = "text-align:right; color: darkred;float:left;"> Student: <select> <option value = "Select"> Select</option>} <option value = "one"> 1</option>} <option value = "two"> 2</option>} <option value = "three"> 3</option>} </select> Course: <select> <option value = "Select"> Select</option>} <option value = "one"> 1</option>} <option value = "two"> 2</option>} <option value = "three"> 3</option>} </select> Instructor: <select> <option value = "Select"> Select</option>} <option value = "one"> 1</option>} <option value = "two"> 2</option>} <option value = "three"> 3</option>} </select> <input type="submit" value="Assign"> </form><br><br> <hr size = "5" color = "darkgray"> <h4> Delete User</h4> <form name = "DeleteUser" action=" " method= "get" style = "text-align:right; color: darkred;float:left;"> User: <SELECT NAME= FullName> <OPTION VALUE=0>Choose</OPTION> <?php echo $options2; ?> </select> <input type="submit" name="delete" value="delete"> </form><br><br> <hr size = "5" color = "darkgray"> <link rel="stylesheet" href="styles/pecui.css" media="screen" /> </body> </html> <?php ?> This is where the possible issue is if (isset($_POST)) { mysql_query("DELETE FROM useraccess WHERE FullName='$FullName'") or die(mysql_error()); echo "Success!"; } else { echo "Not successful"; } What happens is upon submitting, it just deletes the last 2 records in the table "useraccess" instead of the value selected from the drop down. I'm thinking that its not properly storing the data from the database, which is whats causing the query issue. If anyone could help me, it would be very much appreciated it.

    Delete data in SQL in PHP

    Hi everyone, I don't understand why MySQL won't do execute query to delete record in phpmyadmin. I made a script in PHP, what did I do wrong? First page: <?php session_start(); if ($_SESSION['user']) { echo "<p>You are logging in as ".$_SESSION['user']." <a href='logout.php'>Log out</a></p>"; } else { header('location:denied.php'); } require('require.php'); ?> <!doctype html> <html> <head> <title>Delete your member's information</title> <link href="rcd.css" rel="stylesheet" type="text/css"> <link href="submit.css" rel="stylesheet" type="text/css"> </head> <body> <center> <p>Are you sure you want to delete this member's information?</p> <form action="delete2.php"> <table> <?php $del = $_GET['delete']; $show = "SELECT * FROM Members WHERE ID = '".$del."'"; $result = mysqli_query($Garydb, $show); if (mysqli_num_rows($result)) { while ($rows = mysqli_fetch_assoc($result)) { echo "<tr><td>First Name: </td><td><input type='text' value='".$rows['FirstName']."'></td></tr>"; echo "<tr><td>Last Name: </td><td><input type='text' value='".$rows['LastName']."'></td></tr>"; echo "<tr><td>Birth Month: </td><td><input type='text' value='".$rows['Month']."'></td></tr>"; echo "<tr><td>Email: </td><td><input type='text' value='".$rows['Email']."'></td></tr>"; echo "<tr><td>Local: </td><td><input type='text' value='".$rows['Local']."'></td></tr>"; echo "<tr><td colspan='2'><a href='delete2.php?delete2=".$rows['ID']."' style='font-size:20px;'>Delete Member's Information</a></td></tr>"; } } ?> </table> </form> <p><a href="register.php">Return to register page</a></p> </center> </body> </html> Second Page <?php session_start(); if ($_SESSION['user']) { echo $_SESSION['user']; }else { header('denied.php'); } require("require.php"); if ($_GET['delete2']) { $delete = $_GET['delete2']; } if ($delete) { $del = "DELETE * FROM Members WHERE ID = '".$delete."'"; mysqli_query($Garydb, $del); } ?> <!doctype html> <html> <head> <title>Deleted</title> </head> </html>
  13. I currently have a php code at the top of the page that would automatically delete a user from the database if a certain condition isn't met before 24 hours. This code is processed no matter where you are on the site. I have two questions. 1. Will this be an issue if the database has thousands of users? 2. Is there a better way to do this?
  14. Hi Guys, I have a form where the user can select rows and delete them. But my problem is when I select around 4800 rows to delete it takes too long and also only 2500 rows get deleted. So, could someone help me with the below code so it does not take more time and also deletes all the rows? Note: 1. I use InnoDB 2. I use ajax with async set to false <?php include("dbconnect.php"); ini_set ( 'max_execution_time', 20000); if(isset($_POST['id'])){ foreach ($_POST['id'] as $ids) { $stmt = $dbconnect->prepare("DELETE FROM datatable WHERE id=:id"); $stmt -> bindValue(':id', $ids); $stmt -> execute(); } $data =1; echo $data; } ?> I see in the above code my delete query is executed again and again through the loop and I would like to know if there is a way to execute only one statement and get all the ids inside the statement. Thank you.
  15. Hello PHP Freaks, I think this is just if else statement problem but im kinda lose to it. The whole code is succesful in deleting the data from database the problem is i wanted to put a script that remind the user if he/she really sure to delete the data. By the way this is the script. <?php // connect to the database include 'Connect.php'; // confirm that the 'student_id' variable has been set if (isset($_GET['student_id']) && is_numeric($_GET['student_id'])) { // get the 'student_id' variable from the URL $student_id = $_GET['student_id']; // delete record from database if ($stmt = $mysql->prepare("DELETE FROM student_information WHERE student_id = ? LIMIT 1")) { $stmt->bind_param("i",$student_id); $stmt->execute(); $stmt->close(); } else { echo "ERROR: could not prepare SQL statement."; } $mysql->close(); // redirect user after delete is successful header("Location: Admin_Home.php"); } else // if the 'student_id' variable isn't set, redirect the user { header("Location: Admin_Home.php"); } ?> Please help me modify these codes and where to put the missing line/s of codes.
