Hey I got a question about some PHP code. I was wondering how to do something. I have a form field and Im wanting to set up an if statement so if they dont enter something it will echo something and if they do enter something it will enter something. I know this is probbaly simple but Im just drawing a blank here. Thanks a lot

<pre id=code><font face=courier size=2 id=code>
if ($HTTP_POST_VARS["FormFieldName"] !="" {
echo "Field has a value";
} else {
echo "Field is blank";
}
</font id=code></pre id=code>

Ah well that was easy enough heheh.
Well now Im trying to take that and put it inside quotes. its like this:

$message = "
if ($HTTP_POST_VARS["FormFieldName !="" { echo "Field has a value";} else { echo "Field is blank";}
";

Ive been messing with it with putting periods in different places but I cant figure out how to make that work

Thanks a lot

If you are wishing to echo that line of code precede all instances of " within the string with a
It should also be noted that for some reason this form removes the " and ] from the code. You should ensure that the FormFieldName has these immediately after....

I think the forum took out the character you were trying to type... What it \? If it was then I tried that already and it didnt work. When I did that it actually the PHP and didnt run anything. It just displayed the PHP lines...

Thanks again

OK, I misunderstood your intent.

The forum is removing " and a close square bracket that should come after FormFieldName...

Heh now Im really confused. I see what your talking about that the forum removes the ]. Let me give you a different example of what Im trying to do:

$price = "if ($level == "standard"
{ echo $standard }
if ($level == "advanced"
{ echo $advanced }
if ($level == "premiere"
{ echo $premiere }
if ($level == "enterprise"
{ echo $enterprise }
if ($level == "ecommerce"
{ echo $ecom }";

I want to put that if statement inside a string, but of course if gives me a parse error.

Thanks again

Keith Slater

Eeeek! You really are trying to confuse the PHP parser!

Try:-

$price = "if ($level == 'standard')\n";
$price .= "{ echo $standard }\n";
$price .= "if ($level == 'advanced')\n";
$price .= "{ echo $advanced }\n";
$price .= "if ($level == 'premiere')\n";
$price .= "{ echo $premiere }\n";
$price .= "if ($level == 'enterprise')\n";
$price .= "{ echo $enterprise }\n";
$price .= "if ($level == 'ecommerce')\n";
$price .= "{ echo $ecom }";
