if statement inside a for loop?

[lukeurtnowski]

Im trying to duplicate this

if(!empty($Img1)) {
echo "<a href='".$Image1."' rel='lightbox[$Name]'>";
echo "<img src='".$Image2."' alt='".$Name."' class='thumb'>";
echo "</a>";
echo "\n";
}        
if(!empty($Img2)) {
echo "<a href=".$Image2." rel='lightbox[$Name]'>";
echo "<img src='".$Image2."' alt='".$Name."' class='thumb'>";
echo "</a>";
}    
if(!empty($Img3)) {
echo "<a href=".$Image3." rel='lightbox[$Name]'>";
echo "<img src='".$Image3."' alt='".$Name."' class='thumb'>";
echo "</a>";
}                
if(!empty($Img4)) {
echo "<a href=".$Image4." rel='lightbox[$Name]'>";
echo "<img src='".$Image4."' alt='".$Name."' class='thumb'>";
echo "</a>";
}
if(!empty($Img5)) {
echo "<a href='".$Image5."' rel='lightbox[$Name]'>";
echo "<img src='".$Image5."' alt='".$Name."' class='thumb'>";
echo "</a>";
}
if(!empty($Img6)) {
echo "<a href=".$Image6." rel='lightbox[$Name]'>";
echo "<img src=".$Image6." alt=".$Name."' class='thumb'>";
echo "</a>";
}
?> 

Heres what I have so far, but I get an error

for ($f = 1; $f < 7; $f++) {
    if(!empty(${'Img' . $f})) {
    echo "<a href='".$Image $f."' rel='lightbox[$Name]'>";
    echo "<img src=".$Image $f." alt=".$Name."' class='thumb'>";
    echo "</a>";
    echo "\n";
    }        
} 

Thanks...

is this ok?

$Photos = array(1 => $Img1, $Img2, $Img3, $Img4, $Img5, $Img6);

for ($f = 1; $f < 7; $f++) {
    if(!empty($Photos['f']})) {
    echo "<a href='".$Image. $f ."' rel='lightbox[$Name]'>";
    echo "<img src=".$Image. $f ." alt=".$Name."' class='thumb'>";
    echo "</a>";
    echo "\n";
    }        
}

PHP supports variable variable names, i know that sounds odd.

To state that a name of a variable, is a variable, you must put two dollar signs before the
name of the variable...

I never bothered understanding how does this odd feature works...
you can just simply use arrays with a varible as an index instead, in the following manner:

$img[$i]

k, great, that worked.
Now how come when I do this, only the variable f appears

    echo "<a href='".$Image. $f ."' rel='lightbox[$Name]'>"; 

[welsh]

try:

echo '<a href="' . $Image . $f . '" rel="lightbox[' . $Name . ']">'; 

also, any chance you are using lighbox? ii think it was just your quotes getting mixed up and not having them in the right place cause the $name variable was inside them making it just appear as $name in the html code.
