I want to check to see if there is a empty form varible sent.

I have this code

 

<?php
     if (isset($_POST['what do i put in here if i want to check if posted data is nothing']))
     {
       echo "N/A";
     }
     else
     {
       echo  "<a href='images/".$_POST['photo2']."' target='_blank'><img src='images/".$_POST['photo2']."'      alt='image' width='150' border='0' /></a>";
     }
     ?>

if($_POST['form_variable']){
echo "exists";
}else {
echo "doesn't exist";
}

[dingus]

you would put in the name of the field

 

if you have

<input type="text" name="name">

 

you would put

 

     if (isset($_POST['name']))
     {
       echo "N/A";
     }

Seems strange but i used this code and it works,

Reversed it

 

<?php
     if (!empty($_POST['photo2']))
     {
       echo "<a href='images/".$_POST['photo2']."' target='_blank'><img src='images/".$_POST['photo2']."'      alt='image' width='150' border='0' /></a>";
     }
     else
     {
       echo  "";
     }
     ?>
