delete selected images with the help of checkboxes

delete selected images with the help of checkboxes - php

This is a page where users can edit their uploaded images. There is a checkbox near each image. I want to delete the selected images after user clicks the "delete selected images" button (each checkbox contains the image name as value). How can I do that?
<?php
session_start();
//////////////if user already logged in go to login.php/////////
if (isset($_SESSION['email'] )&& isset($_SESSION['password'] ))
{
} else{header( "Location: login.php" ); }
include('includes/config.php');
if (isset($_POST['esubmit']) ){
$checkbox=$_POST['delete'];
echo $checkbox;
}//main one
if (isset($_POST['esubmit']) ){
} else { $clickeditid=$_GET["id"];
$_SESSION['eid']= $clickeditid ;
}
?>

You have to create a form to submit the data of the checked checkboxes and treate the submited result with the php code : if you want to put the php code on the same page, you can check if there is any data in the POST vars and create a SQL Query to delete the corresponding pictures.
You can find a very well documented tutorial here : http://sharemyphp.wordpress.com/2009/12/21/ajax-jquery-php-multiple-delete-item-with-check-box/

I use the below code to delete images in my admin panel. I saved the file as deletephoto.php. Note that this script works without login. You need to make some changes to fit your use case
<form method="post" action="deletepho.php">
<center>
<input type="submit" value="Delete" name="Delete">
</center>
<?php
\\lets assign the folder name in $title
\\You can assign any name
$title= "test";
\*$directory corresponds to whole path. Edit to your preference. (i assume u store your
images in directory named "images") */
$directory = "$title/images";
\\The array specifies the format of the files
$allowed_types=array('jpg','jpeg','gif','png');
$file_parts=array();
$ext='';
$title='';
$i=0;
$dir_handle = #opendir($directory) or die("There is an error with your image directory!");
while ($file = readdir($dir_handle))
{
if($file=='.' || $file == '..') continue;
$file_parts = explode('.',$file);
$ext = strtolower(array_pop($file_parts));
$title = implode('.',$file_parts);
$title = htmlspecialchars($title);
$nomargin='';
if(in_array($ext,$allowed_types))
{
if(($i+1)%4==0)
$nomargin='nomargin';
echo'
<div id="picture">
<img src="'.$directory.'/'.$file.'" width="150" height="150"><br>
Select <input type="checkbox" value="'.$directory.'/'.$file.'" name="imgfile[]">
\* I specified input name as an array . So that we can store in an array and delete it.*/
</div>';
}
$i++;
}
closedir($dir_handle);
\\Now we have the list of images within form elements
?>
</form>
Now here is the actual code to delete the photos. I saved it as deletepho.php.
$file = $_REQUEST['imgfile'];
$num_files=count($file);
for($i=0;$i<$num_files;$i++)
{
unlink ("$file[$i]");
}
echo "Images successfully deleted.Go <a href='deletephoto.php'>back</a>";

I can't update MySQL PHP

Your code is not working because you haven't sent in
<form action="prosesstatus.php" method="post">
Parameters:
$idPemohon = $_GET['idPemohon'];
$idkursus = $_GET['idkursus'];
$idPemohonan =
$_GET['idPemohonan'];
If you want use $_GET link should look like:
prosesstatus.php?idPemohon=value&idkursus=value&idPemohonan=value
Or you should add these parameters in
Input type hidden and change in php to $_POST
I agree with others than you should use MVC for example some kind of framework (Laravel, CodeIgniter)
Or separate as much as possible php and html because your code looks unprofessional.
Your MySQL queries are vulnerable to SQL injection and most likely file
include/connect.php
is not outside public folder which is not good practice to do.

dynamically added link are not triggering in php

I have added images and the corresponding links to the database and viewed on index page, problem is when i click the images it goes to the present page, it does not open corresponding links related to images. But same is working fine in marquee.
code for adding images and links is
<?php
include_once("../init.php");
validation_check($_SESSION['UID'], SITE_HOME_ADMIN);
$msg='';
if(isset($_POST['save']))

$insertSql =("INSERT INTO videonews (videourl)
VALUES ('$videourl')");
$insertSql="INSERT INTO ".VIDEONEWS." SET
`adv_url` = '".realStrip($_POST['adv_url'])."'";
$query = mysql_query($insertSql);
$adv_id = mysql_insert_id();
$adv = '';
if($_FILES["adv"]['name']!= ''){
$fileData = pathinfo(basename($_FILES["adv"]["name"]));
$adv = $adv_id . '_adv.' . $fileData ['extension'];
move_uploaded_file($_FILES["adv"]["tmp_name"], $upDir . $adv);

First thing you should do is to protect yourself from SQL injection, read about it.
I think your problem lies here:
$adv = ''; ///you set $adv equal to empty string
if($rs['adv']!='') { //VVVV here you try to use your empty string
$adv = '<img src="'.$adDir.$rs['adv'].'" style="width:250px; height:150px" > ';
}
I believe it should be
//VVVVVV
$adv = '<img src="'.$adDir.$rs['adv'].'" style="width:250px; height:150px" > ';

Adding PHP comment box to my site

Hi i've managed to make some sort of a comment box that relies on the use of a mysql database and php coding. I'm able to run the comment box by opening its index.php file on my server but when i try adding it to a html page by using a simple include_once php code
it doesn't seem to work.
please excuse me if I sound stupid but this is my first time using php.
here is the code i've been trying to use.
<?php
include_once("../connect.php");
$commenting_form = '<form action="addcomment.php" method="post">
<table width="310" border="0" cellspacing="0" cellpadding="0">
<tr>
<td colspan="2"><strong>Add Comment:</strong></td>
</tr>
<tr>
<td width="105">Title</td>
<td width="205"><input type="text" name="msg_title" id="msg_title" style="width:200px;" /></td>
</tr>
<tr>
<td colspan="2"><textarea name="msg_message" id="msg_message" style="width:100%;height:200px;font-family:Courier New">Message</textarea></td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="Add Comment" name="msg_submit" id="msg_submit" /></td>
</tr>
</table>
</form>';
$get_comments = mysql_query("SELECT * FROM comments");
$comments_count = mysql_num_rows($get_comments);
if ($comments_count>0)
{
while ($com = mysql_fetch_array($get_comments))
{
$id = $com['id'];
$title = $com['text'];
$message = $com['message'];
$comment .= '<strong>'.$title.'</strong><br />'.$message.'<hr />';
}
$comment .= $commenting_form;
$page_title = $comments_count.' Comments';
}
else
{
$comment = 'There are no comments at the moment.<br />'.$commenting_form;
$page_title = 'No Comments';
}

Try this:

Nothing is happening here. Please suggest

You will find I have added the session_start() at the very top of the page. I have also removed the session_start() call later in the page. This page should work fine.

I had the same issue, but my solution wasn't as obvious as the suggested ones. It turned out that my php-file was written in UTF-8, which caused issues. I copy/pasted the content of the entire file into a new php-file (Notepad++ tells me this is written in ANSI rather than UTF-8), and now it work flawlessly.

The answer is above by Ross.
Firstly, putting session_start() as the first line of code will mean that you cannot deserialise any objects correctly into session variables.
The reason for getting this issue is 99% likely to be trailing spaces at the end of your include files (yes - I know it sounds unlikely but just try it). The offending file is in the error message. I wanted to back up Ross answer which worked for me but this site is counter intuitive.
IGNORE the nonsense answers. Remove the trailing spaces, newlines etc... and all will be well. ROSS knows what he is talking about.
Putting session_start() at the top of your file DOES work but it isnt the correct solution.

replace session_start(); with #session_start(); in your code

This should solve your problem. session_start() should be called before any character is sent back to the browser. In your case, HTML and blank lines were sent before you called session_start(). Documentation here.
To further explain your question of why it works when you submit to a different page, that page either do not use session_start() or calls session_start() before sending any character back to the client! This page on the other hand was calling session_start() much later when a lot of HTML has been sent back to the client (browser).
The better way to code is to have a common header file that calls connects to MySQL database, calls session_start() and does other common things for all pages and include that file on top of each page like below:
include "header.php";
This will stop issues like you are having as also allow you to have a common set of code to manage across a project. Something definitely for you to think about I would suggest after looking at your code.
<?php
session_start();
if (isset($_SESSION['error']))
{
echo "<span id=\"error\"><p>" . $_SESSION['error'] . "</p></span>";
unset($_SESSION['error']);
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">
<p>
<label class="style4">Category Name</label>
<input type="text" name="categoryname" /><br /><br />
<label class="style4">Category Image</label>
<input type="file" name="image" /><br />
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
<br />
<br />
<input type="submit" id="submit" value="UPLOAD" />
</p>
</form>
<?php
require("includes/conn.php");
function is_valid_type($file)
{
$valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif", "image/png");
if (in_array($file['type'], $valid_types))
return 1;
return 0;
}
function showContents($array)
{
echo "<pre>";
print_r($array);
echo "</pre>";
}
$TARGET_PATH = "images/category";
$cname = $_POST['categoryname'];
$image = $_FILES['image'];
$cname = mysql_real_escape_string($cname);
$image['name'] = mysql_real_escape_string($image['name']);
$TARGET_PATH .= $image['name'];
if ( $cname == "" || $image['name'] == "" )
{
$_SESSION['error'] = "All fields are required";
header("Location: managecategories.php");
exit;
}
if (!is_valid_type($image))
{
$_SESSION['error'] = "You must upload a jpeg, gif, or bmp";
header("Location: managecategories.php");
exit;
}
if (file_exists($TARGET_PATH))
{
$_SESSION['error'] = "A file with that name already exists";
header("Location: managecategories.php");
exit;
}
if (move_uploaded_file($image['tmp_name'], $TARGET_PATH))
{
$sql = "insert into Categories (CategoryName, FileName) values ('$cname', '" . $image['name'] . "')";
$result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error());
header("Location: mangaecategories.php");
exit;
}
else
{
$_SESSION['error'] = "Could not upload file. Check read/write persmissions on the directory";
header("Location: mangagecategories.php");
exit;
}
?>

use ob_start(); before session_start(); at top of your page like this
<?php
ob_start();
session_start();

For others who may run across this - it can also occur if someone carelessly leaves trailing spaces from a php include file. Example:
<?php
require_once('mylib.php');
session_start();
?>
In the case above, if the mylib.php has blank spaces after its closing ?> tag, this will cause an error. This obviously can get annoying if you've included/required many files. Luckily the error tells you which file is offending.
HTH

Generally this error arise when we send header after echoing or printing. If this error arise on a specific page then make sure that page is not echoing anything before calling to start_session().
Example of Unpredictable Error:
<?php //a white-space before <?php also send for output and arise error
session_start();
session_regenerate_id();
//your page content
One more example:
<?php
includes 'functions.php';
?> <!-- This new line will also arise error -->
<?php
session_start();
session_regenerate_id();
//your page content
Conclusion: Do not output any character before calling session_start() or header() functions not even a white-space or new-line

Just replace session_start with this.
if (!session_id() && !headers_sent()) {
session_start();
}
You can put it anywhere, even at the end :)
Works fine for me. $_SESSION is accessible as well.

use session_start() at the top of the page.
for more details please read the link session_start

I was able to solve similar Warning: session_start(): Cannot send session cache limiter - headers already sent by just removing a space in front of the <?php tag.
It worked.

I had a website transferring from one host to another, it seemed to work fine on the old host but a few pages on the new host threw the error Warning: session_start(): Cannot send session cache limiter - headers already sent
while I always kept the
&lt?php
session_start();
at the top of the page no spaces and nothing inserted before
it really bugged me that I stared every page with the session opening, and it worked on some pages and run through a bug on others
I picked the pages that had the problems, backed them up, created new blank pages and simply copied and pasted the code as is, saved and uploaded and boom, problem gone!
this is something you guys may need to consider, it may have been the encoding of the page, or something, not sure the exact source of the problem, but here is a fix to look at in case you guys run into a similar problem
cheers!

In my case I had to set the file encoding without BOM.

This started for me when I redirected my site to https:// (for SSL Certificate). From my experience with this issue, the session_start() had to be before the browser saw any HTML code. For my example, I was using session_start() in nav.php to determine the options of the navigation bar. I ended up placing session_start() right after the php comments in the index.php file and every page which called nav.php. I was able to keep the php comments before session_start() but could not keep the HTML comments above the php.

Check any extra space before php tag.

div coming down while refreshing the page

I want to make a page for android which is refreshing in every sec . All things are working well but the problem i am facing on this page when you click on the reserve button then entire div come down and leave a small space above but after next refresh it becomes ok . I have tried without div but its not working Here is the code
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<?php
Header('Refresh:2;url=http://medical.gofreeserve.com/and/checkm.php');
?>
<head>
<style type="text/css">
<!--
.style2 {color: #FFFFFF}
-->
</style>
</head>
<body bgcolor="#000000">
<?php
include("../common/connection.php");
?>
<?php
if(isset($_GET['reserve']))
{
echo $sql = "UPDATE newsevents SET booking ='1' WHERE news_id='$_GET[val]'";
$query = mysql_query($sql) or die(mysql_error());
}
$new_query=mysql_query("select * from newsevents where booking=0") or die(mysql_error());
while($row=mysql_fetch_array($new_query))
{
$id=$row['news_id'];
$date=$row['date'];
$news_text=$row['text'];
?>
<div style="border-bottom:2px solid #FFFFFF" >
<form name="fm1" action="checkm.php" method="get">
<table width="95%">
<tr>
<td width="60%" height="50" ><span class="style2"><?php echo $date ?></span></td>
<td width="40%"><span class="style2"><?php echo $news_text ?></span></td>
<td width="40%"><span class="style2"><input type="hidden" name="val" value="<?php echo $id?>" / ></span></td>
<td width="30%"><input type="submit" name="reserve" id="reserve" value="reserve" /></td>
</tr>
</table>
</form>
</div>
<?php }?>
</body>
</html>

You're echoing the SQL statement when running the SQL query, which is pushing down the div. Just use the following instead:
if(isset($_GET['reserve']))
{
$sql = "UPDATE newsevents SET booking ='1' WHERE news_id='".$_GET['val']."'";
$query = mysql_query($sql) or die(mysql_error());
}
