Count image nodes, and print number

JonGirard - November 3, 2008 - 04:11

Hi,

I want to be able to display the number of image nodes that are on the site, in numeric form. (EX: if there are 103 image nodes on the site, then print the number "103.")

I looked into the count function, and found something like this. I placed it where I wanted the number to print on my page..

 <?php
  $node_types = node_get_types('image');
  print("<ul>\n");
  foreach ($node_types as $type => $name) {
    $count = db_result(db_query("SELECT COUNT(*) FROM {node} WHERE type = 'image'", image));
    print("<li>$name  : $count</li>\n");
  }
  print("</ul>");
?>

but it doesn't work for me.

Any help is appreciated,

Jon.

You have some "extra" code

You have some "extra" code in there, not sure if it is causing a problem, here is a simpler version.

 <?php
  print("<ul>\n");
  $count = db_result(db_query("SELECT COUNT(*) FROM {node} WHERE type = 'image'"));
  print("<li>image  : $count</li>\n");
  print("</ul>");
?>

Thanks, that works great

Thanks, that works great now.

I've thought about it further though, and I'd like to take it one step further, and output that number onto a dynamically created PNG image. I've gotten to the point where the image generates fine, and I can put text on it, but I can't seem to get the count number to print on it.

This is the code I'm attempting to use in "imagecreate.php" which I've placed in my site folder..

<?php
header("Content-type: image/png");
$im = @imagecreatefrompng("sites/all/themes/BDC/tab_parentcounter.png");
$text_color = imagecolorallocate($im, white);
imagestring($im, 5, 12, 12,  print ("$count"), $text_color);
imagepng($im);
imagedestroy($im);
$count = db_result(db_query("SELECT COUNT(*) FROM {node} WHERE type = 'image'"));
?>

Is this possible to do?

Thanks,

Jon

A multitude of issues,

A multitude of issues, print("$count") should be simply $count, you need to set $count before you use it. The big problem though is without some extra code it will simply not work since db_result, db_query and the connection to the database has not been made. Search for "bootstrap" for solutions to this.

Another approach is to call the script as imagecreate.php?count=3 (or some number) then at the start of the script do $count = $_GET['count']. The code that creates the link would then do the db work.

I searched bootstrap, and

I searched bootstrap, and looked as if it would be something which would really require me to dive in deep, no?

Thus, I gave the second approach a try, and it seems to work pretty well.. Still though, I'm completely stumped with a few things:

1) In my style.css for a menu item, I'm calling the dynamic image: "#block-menu-184 ul.menu li.leaf {
background-image:url(/sites/all/themes/BDC/imagecreate.php?count=);"

Of course, the problem is since style.css is a seperate file, I'm not sure how I'd get the dynamic number to print beside the "=" in the url (currently as you can see I just have it as "?count=")

It's looking as if I'll have to go with the original bootstrap way most likely I'm guessing..?
