PHP - Call A Script When Directly Accessing An Image In The Browser

Well the subject line is pretty explicit.  I found this script that uploads a picture onto a folder on the server called images, then inserts the the path of the image on the images folder onto a VACHAR field in a database table. 
Code: [Select]




<?php

//This file inserts the main image into the images table.

//address error handling

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE);





//authenticate user
//Start session
session_start();

       
        //Connect to database
require ('config.php');

//Check whether the session variable id is present or not. If not, deny access.
if(!isset($_SESSION['id']) || (trim($_SESSION['id']) == '')) {
header("location: access_denied.php");
exit();
}

        else{ 







// Check to see if the type of file uploaded is a valid image type

function is_valid_type($file)

{

     // This is an array that holds all the valid image MIME types

     $valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif");

 

     if (in_array($file['type'], $valid_types))

         return 1;

     return 0;

}

 

// Just a short function that prints out the contents of an array in a manner that's easy to read

// I used this function during debugging but it serves no purpose at run time for this example

function showContents($array)

{

     echo "<pre>";

     print_r($array);

     echo "</pre>";

}

 

// Set some constants

 

// This variable is the path to the image folder where all the images are going to be stored

// Note that there is a trailing forward slash

$TARGET_PATH = "images/";

 

// Get our POSTed variable

$image = $_FILES['image'];

 

// Sanitize our input

$image['name'] = mysql_real_escape_string($image['name']);

 

// Build our target path full string.  This is where the file will be moved to

// i.e.  images/picture.jpg

$TARGET_PATH .= $image['name'];

 

// Make sure all the fields from the form have inputs

if ( $image['name'] == "" )

{

     $_SESSION['error'] = "All fields are required";

     header("Location: member.php");

     exit;

}

 

// Check to make sure that our file is actually an image

// You check the file type instead of the extension because the extension can easily be faked

if (!is_valid_type($image))

{

     $_SESSION['error'] = "You must upload a jpeg, gif, or bmp";

     header("Location: member.php");

     exit;

}

 

// Here we check to see if a file with that name already exists

// You could get past filename problems by appending a timestamp to the filename and then continuing

if (file_exists($TARGET_PATH))

{

     $_SESSION['error'] = "A file with that name already exists";

     header("Location: member.php");

     exit;

}

 

// Lets attempt to move the file from its temporary directory to its new home

if (move_uploaded_file($image['tmp_name'], $TARGET_PATH))

{

     // NOTE: This is where a lot of people make mistakes.

     // We are *not* putting the image into the database; we are putting a reference to the file's location on the server

     $sql = "insert into images (member_id, image_cartegory, image_date, image) values ('{$_SESSION['id']}', 'main', NOW(), '" . $image['name'] . "')";

     $result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error());

     header("Location: images.php");

echo "File uploaded";

     exit;

}

else

{

     // A common cause of file moving failures is because of bad permissions on the directory attempting to be written to

     // Make sure you chmod the directory to be writeable

     $_SESSION['error'] = "Could not upload file.  Check read/write persmissions on the directory";

     header("Location: member.php");

     exit;

}







        } //End of if session variable id is not present.
 


?> 


The script seems to work fine because I managed to upload a picture which was successfully inserted into my images folder and into the database.
Now the problem is, I can't figure out exactly how to write the script that displays the image on an html page. I used the following script which didn't work.


Code: [Select]

//authenticate user
//Start session
session_start();

       
        //Connect to database
require ('config.php');

$sql = mysql_query("SELECT* FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main' ");
$row = mysql_fetch_assoc($sql);
$imagebytes = $row['image'];
header("Content-type: image/jpeg");
print $imagebytes;







Seems to me like I need to alter some variables to match the variables used in the insert script, just can't figure out which.  Can anyone help??

Any help is appreciated

Hello all, I'm new to PHP and to these forums and i'm having trouble with a little script I'm working on.

I have to point out at the start that the script actually works, other than for the error I'm reporting.

What it does, is lets the user upload an image to the server and creates a thumbnail imageof it in another folder. This works as intended. (I.e. the images gets uploaded and the thumbnail is created) The issue i'm having is when the work is completed successfully...

If there's an error, I update a variable $msg with an error mesage. (File too large, or invalid filetype) If this is the case, the script will render the html code correctly, display the error, then redirect you using javascript after 4 seconds to the original page.

No worries here, everything works so far.

However, if there is no errors to report and the script is successfull, I update $msg to say "it worked"(or whatever) but instead of displaying the formatted webpage displaying the message, then redirecting after 4 seconds, all that happens is the html code is displayed instead.

(If I cut and paste this code into a new htmlfile, it renders correctly.)

Attached below is the php code which does all the work. (But not the main php file which calls it)

Can someone please point me in the right direction as to what I'm doing wrong! lol

(Again, I'm new here so a big hello from me!!!)

I am trying to develop a browser interface for an embedded system.  The code written so far consists of one HTML page and one PHP script.  The HTML page creates a form containing a select widget and a submit button.  When the submit button is pressed, the selected item is posted to the PHP script for processing.  The PHP script does a MySQL query using the form data and generates HTML to display the query result in a table, which displays in a new Web page.  All of this works fine.  However...

I need to change the HTML page to create the select widget choices using a the result of a query run when the HTML page gets displayed.  I created a PHP script to do this, and included it in my HTML page in this manner:

Code: [Select]
<form action="procSomeForm.php" method="post">
    <?php
          include "genSelectList.php";
    ?>
   <input class="main" type="submit" name="submit[view]" value="View" style="width:70px"/>
</form>

When I tried this, the select didn't appear.  I tried moving the <select> </select> out of the PHP script and placing them around the "include".  The select now displayed but with no contents.  After many failed attempts to resolve any errors in the script, I began to suspect that the browser was ignoring the include directive.  I then reduced the problem to this trivial code:

Code: [Select]
<html>
<head>
<title>PHP Test</title>
</head>

<body>
    <?php
        include "tmp.php";
        echo "<p>This message brought to you by PHP!</p>";
    ?>

</body>
</html>

The PHP script looks like this:

Code: [Select]
<?php
echo "<p>Hello from tmp.php!</p>";
?>

My Web browser rendered the result as:

Code: [Select]
This message brought to you by PHP!

";?>

The "hello" message in tmp.php wasn't displayed, and the the browser printed the last few characters of the embedded PHP statement as if they were simple text!

I have tried this same experiment on two PCs with the same result.  My development PC runs Debian 6.0 (Squeeze) in VMWare on top of WinXP; I access the Web pages locally from within VMWare using IceWeasel.  My embedded PC also runs Debian 6.0; I access the Web pages  from my WinXP box using Firefox.  Interestingly, when I use IE8 to call up the trivial page from the embedded PC, it displays a blank page!

Sorry for the long-winded setup to the problem, but I wanted to point out that generating a separate HTML page from a PHP script works; it appears that the issue is with putting PHP statements in an HTML page.

Any help will be greatly appreciated - thanks in advance!

QUESTIONS:

1. I need to call the RequestTicket method and pass the XML string to it.
   I don't know how to do it here(pass the method name to call).

2. For client authentication they gave us three certs, one root cert, one intermediate
   cert and a client authentication cert PROTPLUSSOL_SSOpem(it was a .pfx file). Since we are on linux we converted them to pem . In curl calls I could not find way to how to include both the root cert and the intermediate cert ,so I combined them by making a new pem file and copying the intermediate cert and them the root cert and naming it authority.pem .
I am not sure whether it works or not and would like your opinion.

3. For the current code Iam getting the error
   Error no : 77 Curl error: error setting certificate verify locations: CAfile: /home/pps/authority.pem CApath: /home/pps/

 
  If I disable the curl error message,I am getting blank page with page title 403 - Forbidden. Access is denied.

  If I comment out the CURLOPT_CAPATH and CURLOPT_CAINFO lines it gives http 500 error page with the message as content and the following at the top.

 > HTTP/1.1 500 Internal Server Error. Cache-Control: private Content-Type: text/html Server: Microsoft-IIS/7.5 X-AspNet-Version: 1.1.4322 X-Powered-By: ASP.NET Date: Thu, 02 Sep 2010 14:46:38 GMT Content-Length: 1208

If I comment out as above and also CURLOPT_SSLCERT and CURLOPT_SSLCERTPASSWD it gives 403 error with the message as content.

So I would request you to help me out by pointing out whats wrong with the current code.

Thank you.

I can call the following function successfully as a single php program

Hi,

I have some jQuery tabs. I would like to be able to link to them directly, but I can't work out how to do this.

I have the following code:  

<div class="container-outer">

  <div class="container">

    <div id="prod-tabs">

      <ul class="tabs">

        <li class="first_tab"><a href="#tab1">Tab 1</a></li>

        <li><a href="#tab2">Tab 2</a></li>

        <li><a href="#tab3">Tab 3</a></li>

      </ul>

    </div>

    <div class="tab_container">

      <div id="tab1" class="tab_content"> tab 1 </div>

      <div id="tab2" class="tab_content"> tab 2 </div>

      <div id="tab3" class="tab_content"> tab 3 </div>

    </div>

  </div>

</div>

</div>

    How could I link directly to each of the tabs?

Thanks!

Hi, im using colorbox(basically like lightbox) for some links on my site. When a user clicks the link it opens this lightbox. But if they type the link into the address bar manually it takes them to the actual page(which isnt formatted properly). Is there a way to open up the lightbox when they enter the address manually? or a work around?

I hope someone can help me out with this. What I would like to do is import a text file dircetly to a text area. I can't seem to find any examples on this (Yes I did search Google). I know how to upload but I'm not interested in storing files on the server - but rather just importing them directly to a textarea.

Can anyone point me in the right direction?

I can upload:

<form enctype="multipart/form-data" action="uploader.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>


I can read:

$myFile = "testFile.txt";
$fh = fopen($myFile, 'w')


But I'm not interested in either of these as they are unnecessary steps (or are they?). Is there not a way to simply browse/import a text file directly to a textarea  (or anywhere for that matter) without having to actually save the file to the server?

Something like this:

<form enctype="multipart/form-data" action="uploader.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>



//uploader.php

if (isset($_POST['submit'])) {

        $content = $_POST['"grab the contents of the file"'];
        echo "<textarea>";
        echo $content;
        echo "</textarea>";
}

I'm trying to figure out a way to post data directly to a URL. For example:



<?php 
if (isset($_POST["pass"]) && ($_POST["pass"]=="$password")) {

echo "You did it";

?>

<?php 
}
else
{
  echo "<form method=\"post\"><p align=\"left\">";
  echo "<input name=\"pass\" type=\"text\" size=\"25\" maxlength=\"40\"><input value=\"Enter Pass\" type=\"submit\"></form>";
 exit;
} 
?>


Let's assume $password is 'password'. Why can't I simply pass the information through the URL to access the page with something like this:

Code: [Select]
http://mypage.com/the-same-page.php?pass=password

Trying to figure out what's best practice when it comes to parsing XML and echoing it into a pretty little table.

should I save all the data in a array and then loop through the array? Or should I just echo the data directly from the XML file?

Any thoughts would be welcomed. 

Hi all,
