Hey People!

 

I'm saving & uploading images from a form into a data table.

the image name is being changed into "datetime_imagename.jpg" when i select multiple images they are comma seperated.

 

what is the best way to display these?

I'm ok with a single image but multiple im struggling finding much info online. (doubt i know enough to find what im looking for)

You should change your table structure to store ONE and only ONE image name in a table column. If you have multiples of them for a single user/date, etc you need to have an "image table" just to store the names, all linked back to that user/date, etc. Never store data in a table as a comma-separated value.

the names of the images wont conflict.

it does go date/time/minute/second.

When people don't provide code, we can only call out things that sound hinkey.

 

Regardless, you are complicating something that is simple.

 

You display images in a browser using the img tag.

 

Whether you stored one image file or many in a specific row, that is not going to change the fact that each individual image you want to display on a web page has to be available in the src= param of the the img tag.

 

With that said, as ginerjm advised, it's a lot easier to write an img helper script if you have a solid table structure with one image per row referenced.  Then you tend to write something like:

 

// getimg.php
 
$id = (int)$_GET['id];
$sql = "SELECT * FROM images WHERE id = $id";
 
//query for image row
 
if ($found) {

  $fp = fopen($row['filepath'], 'rb');
  //Determine right header -- jpeg example here
  // ....
  $imgMimeType = 'image/jpeg';
  header('Content-Type: ' . $imgMimeType);
  header("Content-Length: " . filesize($row['filepath']));

  fpassthru($fp);
  exit;
   
} else {
  //return data for default img.  Remember this is returning image data, so you have to return a valid image.
}

Then of course where you want to display the images you will have markup like this in your output script:

 

 

echo '<img src="getimg.php?id=' . $images_id  . '">';

I'm using a joomla product call chronoforms attempting to save each file name seperatly into field14/15/16 etc now.

The above is over my head.

 

I had done the below code a few years back (basic but worked)

i updated a program called "jumi" and it now no longer works

 

 
<?php
DEFINE ('DB_USER', 'username');
DEFINE ('DB_PSWD', 'password');
DEFINE ('DB_HOST', 'localhost.site.com');
DEFINE ('DB_NAME', 'username');
$dbcon = mysqli_connect(DB_HOST, DB_USER, DB_PSWD, DB_NAME);
if (!$dbcon) {
die('error connecting to database');
$sqlget = "SELECT * FROM `xtgt` ORDER BY `VIN` ASC";
$sqldata = mysqli_query($dbcon, $sqlget) or die('error getting');
}
echo '';
$sqlget = "SELECT * FROM `xtgt` ORDER BY `VIN` ASC";
$sqldata = mysqli_query($dbcon, $sqlget) or die('error getting');
while($row = mysqli_fetch_array($sqldata, MYSQLI_ASSOC)) {
Echo "<b>Build Number:</b><br> ".$row['VIN'] . " <br>";
Echo "<b>Engine Code:</b> ".$row['engine'] . " <br>";
Echo "<b>Trim Code:</b> ".$row['trim'] . " <br>";

$size = getimagesize("$image1");
$height = $size[1];
$width = $size[0];
     if ($height > 150)
          {
               $height = 150;
               $width = 190;
          }
     else if ($width > 150)
          {
               $height = 150;
               $width = 190;
          }

They are currently still saving comma seperated into file14.!

 

Input_upload1/2/3 are file14/15/16 I noticed that after i had posted the forum won't allow me to edit it.

I have no idea what your last two posts are talking about. I will offer my usual tips:

 

1 - turn on php error checking

2 - separate your logic (your php code) from your output (your html code). Makes it easier to read and to maintain

3 - Try and write your questions in clear language and use punctuation so that we can interpret what you are trying to tell us better.

4 - Learn how to spell the word 'separately'.

 

I still stand by my original post - do not store multiple items in one field. That is not how databases are used.
