[PHP] PHP Array question

[R. Van Tassel]

I have an array with image names like:

 

$arrayone = array(1.jpg, 2.jpg);

$arraytwo = array(a.jpg, b.jpg);

 

 

Then I have a variable for each to count the number of elements:

 

$arrayoneElements = count($arrayone);

$arraytwoElements = count($arraytwo);

 

 

I'm using the element variables to control the loop to display all the array
elements.

 

This is it:

 

for($ctr=1; $ctr  $elemcount; $ctr++){

   if($ctr%5){

  echo td width=\20%\a
href=\javascript:popup_pic('.$gallerypath./$arr[$ctr]')\img
src=\.$gallerypath.thumbs/$arr[$ctr]\ alt=\no image\ //a/td;

   }else{

  echo td width=\20%\a
href=\javascript:popup_pic('.$gallerypath./$arr[$ctr]')\img
src=\.$gallerypath.thumbs/$arr[$ctr]\ alt=\no image\
//a/td/tr\ntr;

   }

}

 

 

What I want to do is to only show 20 pictures at a time with a Next link
and a Previous link. For the first 20 only the Next link would show and
whenever the last set would show only the Previous link would. Every other
time both would show.

 

Can someone point me in the right direction on how to count through the
elements until the end and back to display them? I just can't figure it out.

 

Thanks,

-Roy

sounds like you just might need some paging functions

[PHP] php array question

[Victor C.]

Hi,
I have a line of php that I don't really understand.

foreach($this-orders as $OrderID = $value) {
echo $OrderID.BR;
$OrderObject =$this-orders[$OrderID=$value];
echo $OrderObject-OrderID.--all the sameBR;
}

I know that $this-orders is an array of order objects.

the result i get from this is:

line1. 388--OrderID.
line2. 389--all the same
line3. 389--OrderID.
line4. 389--all the same

I'm really confused about why line 1 and line 3 have different OrderID, but
line 2 and 4 have the same... I've been trying to fix this bug for 3 hrs
with no luck.
Any help would be really appreciated..

Thanks a lot

foreach($this-orders as $OrderID = $value) {
echo $OrderID.BR;
I think Problem is with this line (I am surprised to see it does not
throw a parsing error. As it should !)
$OrderObject =$this-orders[$OrderID=$value];

If $this-orders is an array of order objects then
Following line should be  sufficient 
$OrderObject =$this-orders[$OrderID];
  Or
$OrderObject =$value;

Zareef ahmed
echo $OrderObject-OrderID.--all the sameBR;
}

I know that $this-orders is an array of order objects.

the result i get from this is:

line1. 388--OrderID.
line2. 389--all the same
line3. 389--OrderID.
line4. 389--all the same
