Text field data not passing properly in form POST method

I am working on a digital employment application for my company using HTML and processing with PHP.

The form is defined by:<form method="post" action="./php/post.php" name="empapp"> and the text field is defined by: <input size="13" name="canyoufeelityeah">

My PHP page contains the following lines: `print_r( $_POST); print_r( $_POST["canyoufeelityeah"]);

    if  (($_POST["canyoufeelityeah"] = ' ') or ($_POST["initials2"] = ' ') or ($_POST["initials3"] = ' ') or ($_POST["initials4"] = ' ') or ($_POST["signature"] = ' '))  
    {
        echo $_POST["canyoufeelityeah"]."|".$_POST["initials2"]."|".$_POST["initials3"]."|".$_POST["initials4"]."|".$_POST["signature"]."|";
        echo "You must initial each of the 4 blocks and sign your name at the bottom. <br />You will be redirected to your application in 15 seconds...";
       // echo "<script>setTimeout(\"window.history.back()\", 1500)</script>";
    }`

The printing of all the $_POST variables shows the variable "canyoufeelityeah" with the value, but this section of code always pulls a blank.

Can anyone help out with this? I have approximately 30 other variables that are being passed, but this one is the only one giving me any problems, and I am not sure why.

Thanks!
