 Posted: Fri Sep 27, 2002 8:39 pm Post subject: Two non vds-related questions... |
 |
|
I have two questions that don't really have to do with VDS but I figured someone would probably know at least one of them anyway...
1) How can I get the text from an edit box in HTML with JavaScript?
2) I am a beginner in PHP, and I need to know how to retreive multiple parameters from a URL. (e.x.: noname.com/this.php?parameter1=hi¶meter2=bye)
I am using the following code, but it only will let me retreive one parameter and it must be in the format noname.com/this.php?parameter1:
| Code: | <?
if ($QUERY_STRING == 'parameter1'){
echo "This is parameter1";
}
else{
echo "You did not enter a parameter!";
}
?> |
Thanks for any help!

To question 2:
| Code: |
<?php
echo($parameter1);
echo($parameter2);
?>
|
Please note that if the magic_quotes_gpc option is set on the server, all ' and \ characters
will be automatically prefixed by a \ character by the server. To prevent the \ character
from being output, the stripslashes function could be used like this:
| Code: |
<?php
echo(stripslashes($parameter1));
echo(stripslashes($parameter2));
?>

You're a bit brief on #1 so it's hard to tell what you're really looking for. But here's one way of obtaining the contents of an edit box:
| Code: | <HTML>
<HEAD>
<script LANGUAGE="Javascript" TYPE="text/javascript">
<!--
function Validate(form)
{
if (form.Input.value == "")
{ alert("Enter that input"); form.Input.focus(); return; }
if (form.Input.value != "")
{ alert(form.Input.value); form.Input.focus(); return; }
}
//-->
</SCRIPT>
<TITLE>Test</TITLE>
</HEAD>
<BODY BGCOLOR="#d2d6fc" TEXT="Black" LINK="Blue" VLINK="#551A8B" ALINK="#EE0000">
<FORM Method="POST" Action="">
Input: <INPUT NAME="Input" size=40>
<HR>
<INPUT TYPE=button VALUE="Show Value" onClick="Validate(this.form)"> <INPUT TYPE="reset" VALUE="Reset">
</FORM>
</BODY>
</HTML> |

This is basicly what I am trying to do (in VDS code):
%%page = "say this is the parameter"
if @equal(%%page,index)
info You entered the parameter!
else
warn You must enter a parameter!
end
exit
Although this PHP code does not work (I think I'm close!):
| Code: | <?PHP
if ($PAGE == 'index'){
print "You have entered the \"index\" parameter.";
}
else{
print "You must enter a parameter!";
}
?> |

I think that variable names in PHP may be case sensitive. You may try this code:
| Code: |
<?PHP
if ($page == 'index')
print("You have entered the \"index\" parameter.");
else
print("You must enter a parameter!");
?>
