[PHP] GD installed but imageFUNCTIONS dont work

[Helmut Ott]

Hi, 
hopefully somebody can help to solve this miracle.

My phpinfo

My provider (and phpinfo) says GD <=1.62 is installed.
But when I run scripts using the php-imagefunctions 
that require gd like 

The lines containing the functions like createImage(), or ImagecolorAllocate() return 
error messages.
How can I find out without doubt whether the functions work properly or not?
Every advice is appreciated.

[PHP] loops with array_walk or foreach using array??? of variable pairs

[Helmut Ott]

I need to run the if-construct below (containing a number of variables in
each "branch") using the 2 variables $table1 and $table2  in each run  for
each combination
Is it array_walk or foreach ? (I "guess" that here I need a 2-dim-array, or
so, passing always these 2 variables with each run:
This expression has to be run using the 2 variables $table1 and $table2 in
each possible combination, which is :


$table1="a"; $table2="x";
$table1="a"; $table2="y";
$table1="a"; $table2="z";
$table1="b"; $table2="x";
$table1="b"; $table2="y";
$table1="b"; $table2="z";

How do I assign these valies to a multidim array and pass pairs of $table1
and $table2 to a foreach() or array_walk loop?

Now this is the construct that shall be looped thru:

For($i=0,$i<$numfields,$i++)
{
If($table1=="a" || $table1=="b" )
{
  if($table1=="a")
{Do this using 4 variables}
  elseif($table1=="b")
{Do that using 6 varuables}
}
elseif($table1=="c")
{
  if($table2=="x")
   {Do this} using 4 variables
  elseif($table2=="y")
   {Do that using 4 variables}
  elseif($table3=="z")
   {Do something else using 6 variables}
}
} //endfor

Thanks for any idea on this.

[PHP] Can PHP top limited Windows Explorer? (Visual not filelistlike Image selectiosn for upload forms)

[Helmut Ott]

Are there any visual Image select solutions for upload forms topping the limited 
Windows Explorer?

If you have an  input type=file the explorer opens and gives you a list of files in 
the directory. Thats nice exept u need to select a specific image from a larger number 
of image files.

Is there any way to get a SELECTABLE list of images shown in a PHP replacement of 
Windows Explorer?

Really curious...

[PHP] Wrong result ("345php.tmp") instead a filepath from

[helmut ott]

I have a page with a html-form headed with 
...ENCTYPE="multipart/form-data" ...

and multiple inputs,e.g.:
"..."
If I select a file,e.g. "abc.jpg" with the path "c:\abc.jpg"
I get a value like "345php.tmp" instead of "c:\abc.jpg".

Any idea what is wrong?
