404找不到$ _Server ['PHP_SELF']

Question

I made a connection with a database to send a form to the data base but when I use my submit-button it says:"Not Found

The requested URL /php/GIP/' $_SERVER['PHP_SELF'] ' was not found on this server."

echo '<td><form action=" \' $_SERVER[\'PHP_SELF\'] \' " method="POST" class="Keuze">
        <select  name="Keuze"> 
        <option>0</option> 
        <option>1</option> 
        <option>2</option> 
        <option>3</option> 
        <option>4</option> 
        <option>5</option> 
        </select> 
        <p><input type="submit" name="submit" value="Bestellen"></p> 
        </form></td>';

How do I fix this so it can find it and if I want to use a different file than this file I already work in how should I do that?

Answer 1

there is couple of things wrong with your string formation.

 action=" \' $_SERVER[\'PHP_SELF\'] \' " 
          ^-----------^---------^---^--- you have escaped the 
 terminating single quotes causing the string to not terminate. 
 also you have escape the single quotes in key association. also
 you have included the variable inside a single quote block causing the 
 variable not to expand. the result is a literal  $_SERVER['PHP_SELF'] ' 
 being displayed.

the proper way to handle this situation would be as follows

echo '<td><form action="' . $_SERVER['PHP_SELF'] . '" .....
