PHP - No Image Statement

does anyone know how to do an if statement in the middle of a gd image so that if a dropdown box is selected it draws different lines...

Code: [Select]
  <label for="height"></label>
  <select name="height" id="height">
    <option value="2.4">2.4</option>
    <option value="2.7">2.7</option>
  </select>
</form>
<?php

require_once('./include/connection.php');
?>
<?php
header ("Content-type: image/png");
?>
<?php
$x1=$_GET['x1'];
$x2=$_GET['x2'];
$y1=$_GET['y1'];
$y2=$_GET['y2'];
$im = @ImageCreate (800, 600)
or die ("Cannot Initialize new GD image stream");
$background_color = ImageColorAllocate ($im, 255, 255, 255);
$line_color = ImageColorAllocate ($im, 0, 0, 0);

// imageline ($im,$x1,$y1,$x2,$y2,$text_color);
//front base line
if "height" = "2.4" 
imageline ($im,50,550,500,550,$line_color);
else 
imageline ($im,50,200,500,200,$line_color);
endif
//front left vertical
imageline ($im,50,550,50,200,$line_color);
//front right vertical
imageline ($im,500,550,500,200,$line_color);
//bottom of apex
imageline ($im,50,200,500,200,$line_color);
//left roof line
imageline ($im,50,200,275,100,$line_color);
//right roof line
imageline ($im,500,200,275,100,$line_color);
ImagePng ($im);

I am still a novice, but I am working on an idea.   I have a table with a field: judges_ccpadv that contains only 3 possible characters = B, R, or N   My desire is to display a simple little icon for any of those 3 characters.   I tried: if ($data['judges_ccpadv'] = "B") {
        echo "<img src='images/b.png'>\n";
}
if ($data['judges_ccpadv'] = "R") {
        echo "<img src='images/r.png'>\n";
}
if ($data['judges_ccpadv'] = "N") {
        echo "<img src='images/n.png'>\n";
}   The output is any image that is not in the if statement. So if "B" is in field, r.png and n.png are both displayed.   What am I doing wrong here? Assistance is greatly appreciated.   Thanks!
 

Hi,   I have the following script which displays a banner image based on a cookie. It also displays a banner if there is no cookie. What I would like to do is to display the banners based on cookies, but instead of displaying the "no-cookie.gif" image, I want to insert some HTML content.   What would be the best way to do this?    

$( document ).ready(function() {

    var acode = getVar('agent');

    if (code) SetCookie("code", code, 1);

    else

        code = ReadCookie("code");

    

    var imgsrc = "images/" + code + ".gif";

    var img = new Image();

    

    img.onerror = function (evt) {

          document.getElementById("headimg").src = "images/no-cookie.gif";

      }

    

    img.onload = function (evt) {

          document.getElementById("headimg").src = imgsrc;

        

      }

   

    

});

  Thanks!

Hi,

I've got a FORM Setup. The form has a current image and an option to add a new image (In place of that image)

The form fields in question are :
Code: [Select]
<input type="hidden" name="image_url" value="<?php echo $row_select_propertyimages['image_url']; ?>" />
<input type="file" name="new_image_url" class="inputfile" />
I've setup an IF Statement, to check that if new_image_url ISNT set, then to keep the current image. Otherwise, overwrite it with new_image_url. When I dont choose to upload a new file, The code works correctly.

The code is as follows.
Code: [Select]
if(empty($_POST['new_image_url'])) {
    $image_url = $row_select_propertyimages['image_url'];
} else {
    $image_url = $_FILES['new_image_url'];
}

The data then gets input to a Database. But at the moment, It is not overwriting what is currently there. Can anyone help me on this?

My full code is :
Code: [Select]
<?php

Many Thanks in advance.

I can log-in, and get to the page with the two links on it. However, once I click one of the links it falls back to the log-in page, and it ends up being a never ending loop.

It's doing this:
Log-In --> Page with links ---> Log-In page again

Should be doing this:
Log-In --> Page with links --> Add Product page or View Products page

I can never get into the the actual sub page.

Just to be clear, the address bar actually shows product=add or product=view, but it still shows the log-in page.
