Why doesn't my script work?
Can anyone tell me why the script below doesn't work. The script does the first bit OK in that when a visitor opens the page for the first time there is no value for $name so the visitor gets a form asking for their name. On submitting, their name should go off to another page(a nearly identical page) which as its getting a value for $name should display some text and the link - however, it doesn't behave as it should, its like its not recieving $name because it displays the html form asking for a name?- although I can see in the URL address location that it has recieved the value for $name. What is going on please, its driving me nuts. Oh yes, nearly forgot, earlier versions I did seemed to pass on not just a name but also the string 'urlencode(Rob Smith)'
Thanks David <HTML> <HEAD> <TITLE> Sample Page </TITLE> </HEAD> <BODY> <?php if ( isset($name) ) { print(" <P>Your name is: $name </P> \n"); $name = urlencode ($name); print("<P>This paragraph contains a <A HREF= \"secondpage.php?name = $name \">link</A>\n"); print(" that passes the name variable on to the next document.</P>\n"); } else { print(" <!-- No name has been provided, so we prompt the user for one. -->"); print(" <FORM ACTION = $PHP_SELF METHOD = GET><br>\n"); print(" Please enter your name: <INPUT TYPE = TEXT NAME = \"name\"><br>\n"); print(" <INPUT TYPE = SUBMIT VALUE = \"GO\">\n"); print(" </FORM><br>\n"); print("Wellcome to our website $name!"); } ?> </body> </html>

If $name is not set, $name won't print out
Hi, David
What error message(s) are you getting? I see one problem in your code, near the bottom. ... else { print(" <!-- No name has been provided, so we prompt the user for one. -->"); print(" <FORM ACTION = $PHP_SELF METHOD = GET><br>\n"); print(" Please enter your name: <INPUT TYPE = TEXT NAME = \"name\"><br>\n"); print(" <INPUT TYPE = SUBMIT VALUE = \"GO\">\n"); print(" </FORM><br>\n"); print("Wellcome to our website $name!"); } ?> </body> </html> The line:print("Wellcome to our website $name!"); could be problematic b/c to be in this part of the code $name is not set. Take that line out. Then see how it runs. -Zig

script problem
Thanks but that doesn't seem to cause an error. The problem was identified as being due to the stupid way I leave spaces around this bit:
$name = name shoud be $name=name works OK now! only a little thing but it makes a big difference Bye David
