    displaying only thumbnail images

    in PHP Coding Help

    Posted

    here is the resize image script 

    $columns     = 5;
$thmb_width  = 120;
$thmb_height = 80;

function resizeImage($originalImage,$toWidth,$toHeight){
    
    // Get the original geometry and calculate scales
    list($width, $height) = getimagesize($originalImage);
    $xscale=$width/$toWidth;

    // Recalculate new size with default ratio
    if ($yscale>$xscale){
        $new_width = round($width * (1/$yscale));
        $new_height = round($height * (1/$yscale));
    }
    else {
        $new_width = round($width * (1/$xscale));
        $new_height = round($height * (1/$xscale));
    }
    // Resize the original image
    $imageResized = imagecreatetruecolor($new_width, $new_height);
    $imageTmp     = imagecreatefromjpeg ($originalImage);
    imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

    return $imageResized;
} 

function generateThumbnails(){
global $thmb_width,$thmb_height;

// Open the actual directory
if ($handle = opendir(".")) {
	// Read all file from the actual directory
	while ($file = readdir($handle))  {

    hi, tired that the images did not display at all. I also realised i didn't include the entire script here is the form part etc..

     

    <?php
// CHANGE PARAMETERS HERE BEGIN
$senderName  = " Holidays From Home "; // Eg.: John's Postcards
$senderEmail = "holidaysfromhome@voluntary.awardspace.co.uk";  // Eg.: john@postcard.com
// Change only if you have problems with urls
$postcardURL = "http://".$_SERVER["HTTP_HOST"].$_SERVER["SCRIPT_NAME"];
// CHANGE PARAMETERS HERE END
$result = 0;
$msg = "";
$msg1 = "";
$pic = "";

function displayPhotos() //edit photos and change image sizes 
{
global $pic;
    $columns = 5;
    $count = 0;
$act = 0;
$act1 = 0;
$sel = 0;
    $checked = 0;
    //Get all thumb files
    $thumbs = glob('thumbs/*_th.jpg');
    // Read all file from the actual directory
    foreach($thumbs as $file)
    {
        $count++;
        //Open row if first record for row
        if($count%$columns==1) { echo "<tr>"; }

        $checked = (isset($pic[1]) && $pic[1]==$count) ? ' checked="checked"' : '';
        //displays the images
        echo "<td align=\"center\">";

    creating thumbnails from uploaded images

    You could add the thumbnail script into the images file i have code here for you to look at. It is actually rather difficult.

    displaying only thumbnail images

    in PHP Coding Help

    Posted

    hi all

    I am finishing off the final touches to my PHP postcard script and want to be able to display thumb file types only

    I have found a script to resize the images but this creates larger ones so i want to be able to switch between the two.

     

    <?php
// CHANGE PARAMETERS HERE BEGIN
$senderName  = " Holidays From Home "; // Eg.: John's Postcards
$senderEmail = "holidaysfromhome@voluntary.awardspace.co.uk";  // Eg.: john@postcard.com
// Change only if you have problems with urls
$postcardURL = "http://".$_SERVER["HTTP_HOST"].$_SERVER["SCRIPT_NAME"];
// CHANGE PARAMETERS HERE END
$result = 0;
$msg = "";
$msg1 = "";
$pic = "";

function displayPhotos() //edit photos and change image sizes 
{
global $pic;
$columns = 5;
$act = 0;
$act1 = 0;
$sel = 0;
  // Open the actual directory
if($handle = opendir("thumbs"))
{
  // Read all file from the actual directory
  while($file = readdir($handle))
  {
   if(!is_dir($file))
   {
    if(isset($pic[1]))
    {
     if($pic[1] == $act1){$sel = "checked";}
     else{$sel = "unchecked";}
     }
    if($act == 0){echo "<tr>";}
    echo "<td align='center'><img src='thumbs/$file' alt='postcard' BORDER =1 /><br/><input type='radio' name='selimg' value='$file,$act1' $sel/></td>"; //displays the images

$act++;
    $act1++;
    if($act == $columns){$act = 0;echo "</tr>";}

       }
    }
  echo "</tr>";
  }    
}
?>

     

    my thumbnail images all end in (_th.jpg) and my large files all end in (.jpg). I am really stuck any help would be much appreciated  :confused:

     

     

    PHP Postcard Notice: Undefined index: Notice: Undefined variable errors

    in PHP Coding Help

    I understand what you mean about $pic but I am unsure as to how to fix it here is line 52:

    echo "<td align='center'><img src='thumbs/$file' alt='postcard'/><br/><input type='radio' name='selimg' value='$file,$act1' $sel/></td>";

     

    In that where would define $pic as a array?

     

    Line 134-5

    <tr><td>Send to (email address):</td><td><div style='color:#f00;font-size:16px;'>$msg1</div><input type='text' name='email' size='30' value='".$_POST["email"]."' /></td></tr>

              <tr><td>Message:</td><td><textarea name='message' rows='10' cols='40'>".stripslashes($_POST["message"])."</textarea></td></tr>

     

    From that It looks to me like it is passing the data through but obviously not.

    The URL is not valid and cannot be loaded

     

    It also states that

    Notice: Undefined index: www.voluntary.awardspace.co.uk in /home/www/voluntary.awardspace.co.uk/Postcard.php on line 25

    Notice: Undefined index: Postcard.php in /home/www/voluntary.awardspace.co.uk/Postcard.php on line 25

    PHP Postcard error help:

    in PHP Coding Help

    Posted

    hi,

    I am developing a PHP Postcard system with Micro-Captcha Security and i get the following errors:

     

    Internal Server Error, this is an error with your script, check your error log for more information.

     

    or the code simply does not send the script I understand based on research that the problems lies with undefined variables:

    I also used a PHP error code to display errors.

    See code below: 

    <?php

session_start();
//check error log
ini_set('display_errors', 1);
ini_set('log_errors', 1);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
error_reporting(E_ALL);

// CHANGE PARAMETERS HERE BEGIN
$senderName  = " Holidays From Home "; // Eg.: John's Postcards
$senderEmail = "chris01@voluntary.awardspace.co.uk";  // Eg.: john@postcard.com
// Change only if you have problems with urls
$postcardURL = "http://".$_SERVER["HTTP_HOST"].$_SERVER["SCRIPT_NAME"]; //problem is here perhaps?
// CHANGE PARAMETERS HERE END
$result = 0;
$msg = "";
$msg1 = "";
$pic = "";
function displayPhotos()
{
global $pic;
$columns = 5;
$act = 0;
$act1 = 0;
// Open the actual directory
if($handle = opendir("thumbs"))
{
  // Read all file from the actual directory
  while($file = readdir($handle))
  {
   if(!is_dir($file))
   {
    if(isset($pic[1]))
    {
     if($pic[1] == $act1){$sel = "checked";}
     else{$sel = "unchecked";}
     }
    if($act == 0){echo "<tr>";}
    echo "<td align='center'><img src='thumbs/$file' alt='postcard'/><br/><input type='radio' name='selimg' value='$file,$act1' $sel/></td>";
    $act++;
    $act1++;
    if($act == $columns){$act = 0;echo "</tr>";}

       }
    }
  echo "</tr>";
  }    
}
?>
