Hello,

 

I have been wrestling with this forth past couple of days and cannot work out what is wrong.

The code below works ok except when I wish to change the picture. Instead of changing the image with the corresponding images it uses the "nopic" image even though the correct image is still in the database.

So for example if I enter some data with one image attached this appears correctly. If I then change the image the old image reverts to "nopic" and the new image is displayed with the latest data. Even though in the database the old image is still present

 

Hope this makes sense

 

What am I doing wrong?

 

offending code below

 

Any help greatly appreciated

 



// Connect to the database 
  
$dbc = mysqli_connect(DB_Host, DB_User, DB_Password, DB_Name); 

  

// Retrieve the user data from MySQL
  
$query = "SELECT * FROM conversation where topic = 'polls' ";
  
//$data = mysqli_query($dbc, $query);

  


echo '<table>';
  


$result = mysqli_query($dbc, $query);  
while ($row = mysqli_fetch_array($result)) 
{
    if (is_file(MM_UPLOADPATH . $row['picture']) && filesize(MM_UPLOADPATH . $row['picture']) > 0) {

echo '<tr><td class="label"></td><td><img src="' . MM_UPLOADPATH . $row['picture'] .
        '" alt="Profile Picture" style="width:75px; max-height:55px;" />

' . $row["quote"] .  '';



}
else {
echo '<tr><td class="label"></td><td><img src=" ' . MM_UPLOADPATH  . 'nopic.png" style="width:60px; maxheight=44px;" />

' . $row["quote"] .  '';


}   
}

echo '</tr>'; 


echo '</table>'
?>

I'm going to guess that the problem is in the code that edits/updates the database. You are perhaps altering the existing image name (adding a space or a cr/lf would be enough) so that the code that outputs the image/nopic no longer finds the corresponding actual image file.

 

What is the rest of your code needed to reproduce this problem, including any code that produces your 'edit' form?

The editing part does delete the old image if a new one is uploaded but it is in a completely different table so I'm assuming this would have no effect.

What I'm currently doing is I'm taking the image from the edited table and adding it to another table. It is this second table that the code posted is referring to. Once I change the image the address for old images remains in the database so I can't understand why it fails to find this as looking at the database it is plainly there!

Below are the three programs that are interacting:

First the edit profile.

The "adding an entry code"

and finally the code to displays any entries. The image should  automatically display here.

Apologies if there is unnecessary code but I think the problem could be anywhere now!

 

<h3>Edit Profile</h3>

Your middle code that inserts into the conversation table has a form with username, topic, and quote fields. It does not have a picture field, so of course there is no picture data in the conversation table.

 

You should have php's error_reporting set to E_ALL and display_errors set to ON in your master php.ini so that php will report and display all the errors that it detects. You should not set error_reporting in your code (except for strictly debugging purposes) and you should certainly not set it to hide any of the types of errors. You will save a ton of time. You would have gotten an undefined error at the reference to $_POST['picture'] that would have alerted you to the problem.

 

Also, if you are making this code for a real site, you need to validate ALL external data that your code receives. In this case your validation logic would have told you that there was no $_POST['picture'] value and your logic would have prevented the insert query from executing without all expected data.

Thanks you very kuch for these omments...

 

but isn't the pigture already there?It automatically appears from

 

{
    if (is_file(MM_UPLOADPATH . $row['picture']) && filesize(MM_UPLOADPATH . $row['picture']) > 0) {

echo '<tr><td class="label"></td><td><img src="' . MM_UPLOADPATH . $row['picture'] .
        '" alt="Profile Picture" style="width:75px; max-height:55px;" />';



}
else {
echo '<tr><td class="label"></td><td><img src=" ' . MM_UPLOADPATH  . 'nopic.png" style="width:60px; maxheight=44px;" />';


}}

 

I then insert it with this line: 

$query = "INSERT into conversation values (0,'$username', '$topic', '$quote', '$row[picture]', NOW())";

 

why does this not work?

oops, I didn't see that the query was using a different value than what the form processing code is producing. That's what you get when you have unnecessary lines of code in your program.

 

There's no guarantee that when the form is submitted that the SELECT query is putting a value into the $row variable. You will need to debug at what point you have expected data and at what point you don't. When you examine the conversation data table directly, does it have the expected values in the correct columns? Since your insert query doesn't list the columns, we have no way of even knowing if the query is formed correctly. Also, echo out that query to make sure that it has the expected values in it.

 

When you say you are changing the image, what exact step/code are you referring to?

Hi PFMaBiSmAd

 

Thanks for all you help! much appreciated.

 

 

The data does go into the correct columns (even the picture column has correct img src address!)

 

I change the image in editprofile (first piece code above)

 

relevant code: 

$old_picture = mysqli_real_escape_string($dbc, trim($_POST['old_picture']));
    
$new_picture = mysqli_real_escape_string($dbc, trim($_FILES['new_picture']['name']));
    
$new_picture_type = $_FILES['new_picture']['type'];
    $new_picture_size = $_FILES['new_picture']['size']; 
    
if (!empty($_FILES['new_picture']['tmp_name'])) {list($new_picture_width, $new_picture_height) = getimagesize($_FILES['new_picture']['tmp_name']);}

 

...

 

<input type="hidden" name="old_picture" value="<?php if (!empty($old_picture)) echo $old_picture; ?>" />
      <label for="new_picture">Picture:</label>
      <input type="file" id="new_picture" name="new_picture" />
      <?php if (!empty($old_picture)) {

So, you are uploading a new profile image.

 

Well, your code is unlinking the old image if it's name is different than the new image name (if they are the same name the new image overwrote the old image) so the old image no longer exists and any rows in the conversation table that contain the old image name won't match any image file.

If you don't want to unlink the old image file when it has a different name then the new image, you would remove the logic or comment out the unlink statement in the code -

 

if (!empty($old_picture) && ($old_picture != $new_picture)) {
              @unlink(MM_UPLOADPATH . $old_picture);
}
