[Phplib-users] Classes, MySQL, Images & phplib

[Mike G. <mi...@op...>]

Hello,

I'm having a bit of trouble convincing a phplib class to produce an
image from a MySQL database..

So far I've got the following:

require("config.php3");
class Image {
	var $db;
	function Image() {
		global $ID;
		$img->db = new Image;
		$sql="SELECT photo FROM WLPphoto WHERE profileID='$ID'";
		$img->db->query($sql);
		while($img->db->next_record()) {
			Header("Content-type: image/jpeg");
			echo $this->db->Record[photo];
    		}
	}
}

config.php3 has the database variables defined (much as they are set in
phpSlash)..

It's been a couple months since I've played with classes, so perhaps
it's just that I'm just a bit rusty..

I'd like to generate a script to pull an image out of a database based
on a $ID number.  This all works fine outside of the phplib environment,
but I can't figure out how to get this class to display any results..

Any suggestions?

Mike

require('config.php');
class Image {
  var $db;
  // Suck in the ID from the GLOBALS array, handy becasue you can chnage
  // the ID at runtime if'n ya want.
  function Image($id = $GLOBALS[ID]) {
    // Above you instance the wrong class (the one you're running,
    // suprising this should have caused an infinate loop)
    // The reason this wasn't working is beacus you never instanced the
    // phplib class
    $this->db = new nameOfdbClass;
    $sql = "blah blah blah"
    $this->db->query($sql);
    while ($this->db->next_record()) {
      header("here's an image");
      print $this->db->Record['photo'];
    }
  }
}

Note that you can ahould be able to run run imageSize() on the sql
refernce adn double check it's image type before sending the header.
Here's chuck of code I have for one project, you'll need to modify it for
your own purposes, but it's an ok example of imagesize()

  function getType() {
    if ($debug) {
      echo "Getting Type";
      echo "image::getType() - type is $this->currImg['imagesize'][2]<br>\n";
    }
    switch ($this->currImg['imageSize'][2]) {
      case 1:
        return("gif");
        break;
      case 2:
        return("jpeg");
        break;
      case 3:
        return("png");
        break;
      case 4:
        return("swf");
        break;
      default:
        return("unknown");
        break;
    }
  }

OK..  My present code looks like this:

require('config.php3');
class Image {
   var $db;
   function Image($ID='$GLOBALS[ID]') {
     $this->db = new DB_Sql;
     $sql="SELECT photo FROM WLPphoto WHERE profileID='$ID'";
     $this->db->query($sql);
     while ($this->db->next_record()) {
       Header("Content-type: image/jpeg");
       print $this->db->Record['photo'];
     }
   }
}

and produces only this:
<html><body></body></html>

I just want to clarify though..  in the example you gave ($this->db = 
new nameOfdbClass;), if I was trying to add this to phpSlash 6.2 
nameOfdbClass; would be DB_Sql (or would it be slashDB?

Both seem to produce the same result for me..  I even tried commenting 
out the header line (Header("Content-type: image/jpeg");) to see if that 
would just echo the raw jpg data..  It didn't..  So something's goofing 
up...

This is useful code..  Likely better than the current upload script 
offers..  However, it is already using imagesize once to insert the data 
(not that you would know that), so there's no need to do it again 
afterwards..

No quotes in the above, it's not working cause $ID is being set to the
string "$GLOBALS[ID]" and not the actual value of the global $ID (as a
side note, this happen becasue you're using single quotes which casue
literal strings, double quotes would have meant that the string would have
been scanned for variable substituion and it would have been ok, but you
would have paid a small performance penalty for that substitution.   This
is where knowing everything about your varibles comes in handy.)

if all youre tables are in the same databse as the phpslash stuff, then
slashDB, else you'll need to make a new subclass of DB_Sql.

Make sure you're not outputing anything before that header() call.  I bet
there's an error creeping in (probably from using the wrong db class)
that's casuing it.  For something liek what you're doing I like to add a
construct like this to the top of my code:

if ($debug && $HTTP_GET_VARS[breakme]) {
  echo "I'm outputing something to break the headers.<br>\n";
  echo "This will allow me to see what exactly I'm sending.<br>\n";
  echo "Including errors :)<br>\n";
}

Also, check to make sure (for debug pruposes) error_reporting is set to
E_ALL.  And FWIW, I'd do a $this->db->nf() and make sure the returned
valus is 1 and if it isn't sending a "not availible" jpeg to the
browser before entering the while() loop.  This ensures that if the script
freaks out and can't find a image in the databse, something is returned to
the user indicating so :)

I tried a stack of different options on this, but these gave me parse 
errors:
	$ID=$GLOBALS[ID]
	$ID="$GLOBALS[ID]"

and these didn't (they gave me identical - but bad results):
	$ID='$GLOBALS[ID]'
	$ID=48

As did this actually:

require('config.php3');
class Image {
   var $db;
   function Image() {
     $ID=$GLOBALS[ID];
     echo "ID $ID";
     $this->db = new proDB;
     $sql="SELECT photo FROM WLPphoto WHERE profileID='$ID'";
     $this->db->query($sql);
     while ($this->db->next_record()) {
       Header("Content-type: image/jpeg");
       print $this->db->Record['photo'];
     }
   }
}

Although this displays properly outside of the class...
     $ID=$GLOBALS[ID];
     echo "ID $ID";

result is:
	ID 48

Hmm..  That is essentially what I'm doing...

Some folks on this list may remember me asking about/talking up a online 
bibliography 6 months or so ago..  It's mostly working now and sitting 
here (still in draft mode):
	http://www.openconcept.ca/WLP/biblio/categories.php3

I'm presently working up the portfolio side (harder to explain), but 
this is what I need the images for...  In anycase, it's all based on the 
6.2 code of phpSlash..

This is usefull..  That way it is easy to make/break code..
http://localhost/WLP/profiles/image.php3?ID=48&breakme=yes

 

However, I can't seem to get any output from within the class..

Putting this in the function and commenting out the header doesn't 
output anything..
     echo "this isn't working";

The URL above does, but.. that isn't managing stuff within the code..

I've got a couple references of phpSlash 6.2 ending Variable.class with:
};  /* end of Variable.class */


and not the ?> which would be standard..  I've never seen a php file 
ended like that before...

In anycase, the whole file now looks like this:

<?php
error_reporting(E_ALL);
require('config.php3');

if ($debug && $HTTP_GET_VARS[breakme]) {
   echo "I'm outputing something to break the headers.<br>\n";
   echo "This will allow me to see what exactly I'm sending.<br>\n";
   echo "Including errors :)<br>\n";
}

class Image {
   var $db;
   function Image() {
		$ID=$GLOBALS[ID];
		$this->db = new proDB;
		echo "this isn't working";
		$sql="SELECT photo FROM WLPphoto WHERE profileID='$ID'";
		echo $this->db->nf();
		$this->db->query($sql);
    	while ($this->db->next_record()) {
			// Header("Content-type: image/jpeg");
			print $this->db->Record['photo'];
     }
   }
}
?>

And results in the following:

Warning: Undefined variable: sitename in 
/usr/local/web/WLP/profiles/config.php3 on line 191

Warning: Use of undefined constant rootdir - assumed 'rootdir' in 
/usr/local/web/WLP/profiles/Variable.class on line 23

Which shouldn't be affecting things when the errors are turned off.. 
Those should be pretty innocent..

Nope this didn't work either..

I can't get this class to output anything..  I must be completely 
missing something pretty big...

I've now got these two lines in the class (which should be putting out 
something), which don't give me an error and aren't providing me with a 
value:
	echo "this isn't working $ID";
	echo $this->db->nf();

ps..  Maybe I just need to put this project off till the new year - ha!

btw.  Happy New Year Everyone!

Umm.. $GLOBALS[] is availible everywhere, isn't it?  It's an alternative
to the 'global' keyword?

I just asked in openprojects:#php and someone remined me that paramters
need to be static (eg: function foo($bar='something')) so Umm I did steer
you wrong at first.  Sorry.

The class looks like it should work as you have it though.. er.. what's
the calling script look like?  I assume you're doing something like:
  include('/path/to/image.class');
  $img = new Image;

? Right ;-)
(Hey, it take me 10 minutes to figure out someone unpluged my computer :)

So a few questions:
- What php version are you using?
- Where exactly does $ID come from?

-n.. the nice thing about New Years Eve is that I can start drinking at 4
in the afternoon and not feel guility.  Wheeeeeee!

ps.. I'm going to make a side trip into proper coding styles becasue I see
a lot of this (Ajay is guilty of this too, hence the parser warnings):
PHP Interperts the following three statements differently:
$array[foo]   // foo is assumed to be a constant
$array["foo"] // "foo" is scanned for variables to substitute before
              // executing the statsment
$array['foo'] // foo is taken as a literal text string

mixing and matching these just don't work, you need to be aware of what
you're using.  In your script you use $GLOBALS[ID] which makes php think
that it should look for a constant named "ID" to use for substituion in
the array, and fails.  My expernice is that php normally makes the right
choice and falls back to a varaible, but can give it the incorrect scope,
hence your problems.. It pays to be extra pedantic about variable scope
and importation becasue this is where most security issues come from, not
to mention by not specficly telling php what kind ofvariable you're using,
icky and hard to trace bugs (like this one) can be introduced.
