or there stuff missing to it :S

<?php 
require_once('settings.php');
checkLogin('1 2');

$id=$_GET["msgs"];
mysql_query("DELETE messages FROM messages WHERE message_id='$id'");
?>

Hi. I have the following code to delete a row when the date has passed.

Code: [Select]
$today = date("dmY");
$vLongDate = date("dmY", strtotime($thisDate));

if ($today > $vLongDate) {
mysql_query("DELETE FROM events WHERE id < '$id'");
}

$today is current date, while $vLongDate is the date that is on my database. Am i doing the if statement correctly??

Hi,
   I have created a table named multipath with database name "mydatabase".. I have created a table to store the data in the tables. Check boxes are created to select one row each to delete. But I am unable to delete the rows. Why??

Here's my PHP code

 
 
<?php
$host="localhost"; // Host name
$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="mydatabase"; // Database name
$tbl_name="multipath"; // 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);

?>
<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">&nbsp;</td>
<td colspan="4" bgcolor="#FFFFFF"><strong>Delete multiple rows in mysql</strong> </td>
</tr>
<tr>
<td align="center" bgcolor="#FFFFFF">#</td>
<td align="center" bgcolor="#FFFFFF"><strong>Path ID</strong></td>
<td align="center" bgcolor="#FFFFFF"><strong>Path</strong></td>
</tr>
<?php
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td>
<td bgcolor="#FFFFFF"><?php echo $rows['path_id']; ?></td>
<td bgcolor="#FFFFFF"><?php echo $rows['path']; ?></td>
</tr>
<?php
}
?>
<tr>
<td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td>
</tr>
<?
// Check if delete button active, start this
if($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.php
if($result){

}
}
mysql_close();

Hey everyone i having some trouble updating records in my databse using checkbox from a form.

I can update the records, but i can't figure out how to remove records at the same time.

I've posted the code that i'm using to update below

foreach($_POST['tag'] as $k=>$l){
$tag = mysql_real_escape_string($_POST['tag'][$k]);

$check_tags = mysql_query("SELECT * FROM file_cats WHERE category='$tag'") or die(mysql_error());
$num_tags = mysql_num_rows($check_tags);

if($num_tags==0){
$add_tag = mysql_query("INSERT into file_cats (fileID, category) VALUES('$fileID', '$tag')") or die(mysql_error());
}
}


This code inserts new records based on what the user checked. If it exist it won't add a new row, if it doesn't exist then it will add a new row. but like i said how can remove a row if the box is no longer checked?

I've tried using

foreach(empty($_POST['tag'] as $k => $l){
       $tag = empty($_POST['tag']['$k'];
}


But that didn't work basically nothing was deleted.

Has anyone done something like this before? if so i would appreciate any help you could give

I have a PHP CRUD application and when i delete a row i need it to delete from the MySQL and the image from the uploads folder as well. I have researched and tried dozens of ways with the unlink option but nothing works. If i take out the unlink from my code it will delete fine from the DB. I am new to coding and PHP so any help would be awesome.

The file_path is correct. The uploads is the name of the folder where the image is stored and the $_POST["image"] is the column name in MySQL where the image name is stored.

delete.php

<?php

	//start PHP session
	session_start();

if (!isset($_SESSION['success']))
{
    header("Location: login_page.php");
    die();
}

// check if value was posted
if($_POST){
 
    // include database and object file
    include_once 'config/database.php';

    $file_path = 'uploads/' . $_POST["image"];
    if(unlink($file_path))
 {
	// delete query
	$query = "DELETE FROM myDBname WHERE id = ?";
	$stmt = $con->prepare($query);
	$stmt->bindParam(1, $_POST['object_id']);
 }
	if($stmt->execute()){
		// redirect to read records page and 
		// tell the user record was deleted
		echo "Record was deleted.";
	}else{
		echo "Unable to delete record.";
    }
}

?>

this is the delete button code

					echo "<a delete-id='{$id}' class='btn btn-danger delete-object'>";
					echo "<span class='glyphicon glyphicon-remove'></span> Delete";
					echo "</a>";

This is the javascript for the delete button as well.

	// delete record
	$(document).on('click', '.delete-object', function(){

		var id = $(this).attr('delete-id');

		bootbox.confirm({
		    message: "<h4>Are you sure?</h4>",
		    buttons: {
		        confirm: {
		            label: '<span class="glyphicon glyphicon-ok"></span> Yes',
		            className: 'btn-danger'
		        },
		        cancel: {
		            label: '<span class="glyphicon glyphicon-remove"></span> No',
		            className: 'btn-primary'
		        }
		    },
		    callback: function (result) {

		        if(result==true){
					$.post('delete.php', {
						object_id: id
					}, function(data){
						location.reload();
					}).fail(function() {
						alert('Unable to delete.');
					});
		    	}
			}
		});

		return false;
	});

 

If you need any other info that would help you help me just let me know and i will get that in here ASAP. Thanks again for any help on this.

No errors come up when I run this but it just doesn't delete the entry.



<?
$rec = $_POST['stock'];
if (!$rec){ 
die ('Please eneter a stock number');
}

$link = mysql_connect("xxxx","xxx","xxx");
mysql_select_db('wadkin', $link) or die( "Unable to select database");

mysql_query("DELETE FROM 'wadkin'.'stocklist' WHERE 'stocklist'.'Stock Number' = $rec")
or die ('Query failed');

mysql_close($link);

?>


Can someone please correct,

(btw I have also tried... "DELETE FROM stocklist WHERE 'Stock Number' = $rec")

Hello everyone I need code for this question    would you help me please..?

Maybe some of the great coders here can help this noob out.
So here is what I have so far:

Code: [Select]
//set age criteria for deletion
$age = 60;

//get current date
$datenow  = date("Y-m-d");

//set the range we want to delete
$delete_range = $datenow - $age;

//get old user_id from users table
$oldusers_users = mysql_query ("SELECT user_id FROM users WHERE lastvisit < $delete_range ");

//get user_id from images table that correspond to users table
$oldusers_images = mysql_query ("SELECT user_id FROM images WHERE $oldusers_users=user_id.images ");

//find folders that correspond to the usernames and delete
$oldusers_files = mysql_query ("SELECT username FROM users WHERE lastvisit < $delete_range ");
//print out username
//$result = mysql_($oldusers_files);
$foldername = mysql_result($oldusers_files, 0);

$sigspath = "sigs/";
unlink($sigspath . $foldername . ".gif/index.php");
rmdir($sigspath . $foldername . ".gif");
//now delete user_id's from database
mysql_query("DELETE * FROM users WHERE user_id=$oldusers_users");
mysql_query("DELETE * FROM images WHERE user_id=$oldusers_images");
unset($oldusers_users, $oldusers_images, $oldusers_files, $foldername, $sigspath );
mysql_close($link);
Right now it is only returning the first entry, not the entire list that meets the criteria.  It does delete that one file though but does not remover the rows from the database.

I am sure the database stuff is jacked up I am really new to that part.  What am I doing wrong here or is there a better way to do this perhaps

I have a webpage where all the database items are displyes in a table format.The table also has a check box.Upon clicking the delete button i need to delete all the items whish has the checkbox checked.
How will i do that

I'm trying to set it so that it will delete an entire populated directory based upon a value in the database then after finishing that to go back and delete that row in the database.  my current code is

Code: [Select]
<?php $page_title = "Central Valley LLC | Photo Addition" ?>
<?php include("header.php"); ?>
<?php include("nav.html"); ?>
<div id="content">
<form action="delprod.php" method="post" enctype="multipart/form-data">
<label for="which">Choose A Product To Remove:</label>
<?php $con = mysql_connect("localhost","phoenixi_cv","centraladmin");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("phoenixi_cvproducts", $con);
$result = mysql_query("SELECT * FROM Products");
echo "<select name=\"which\">";
while($row = mysql_fetch_array($result))
   {
echo "<option ";
echo "value=\"" . $row['id'] . "\">";
echo $row['Name'] . "</option>";
}
echo "</select>";
mysql_close($con);
?>
<br />
<input type="submit" name="submit" value="Submit" />
</form>
</div><!--#content-->
<?php include("footer.html") ?>

and the delete script

Code: [Select]
<?php
$con = mysql_connect("localhost","phoenixi_cv","centraladmin");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("phoenixi_cvproducts", $con);
$result = mysql_query("SELECT id FROM Products WHERE id=$_POST['which']");
$row = mysql_fetch_array($result)


chdir('assets');
chdir('images');
$mydir = $row . '/';
$d = dir($mydir);
while($entry = $d->read())
{
if($entry!="." && $entry!="..")
{
unlink($_POST['which'] . '/' . $entry);
}
}
rmdir($mydir);
$result = mysql_query("DELETE * FROM Producs WHERE id=$_POST['which']");
?>
Thank you in advance for all your help.  any easier ways of approaching this will be welcome as well

At the moment  I am creating a search function for my website.
The approach I have in mind is a pseudo-PHP database. To give an example:

A HTML form will submit the results to a PHP file.

HTML FORM - Colour: Black
PHP RESULT PAGE - if ($_POST['color'] == 'Black') {readfile("./products/black/*.html");}
HTML FORM - Price: <$50
PHP RESULT PAGE - if ($_POST['Price'] == '<$50') {readfile("./products/less50/*.html");}

The problem here is if there is an item that is black and costs less than $50, then its going to be listed twice. There is probably some code I can write to ommit the listing of duplicate entries, but it is probably going to be messy, so I am wondering if its better to use a centralized MySQL database, rather than a pseudo-PHP database? I've never used MySQL and don't know much about it and this is my first real attempt at using PHP.

after cloasing connection of database i still got the values form database.
