if statement

cheo

I want to write some code which "attaches" a hidden value to a dinamically generated form output. I was thinking of doing it in a different file and use require in the one I want the output to be placed. A form has a drop down with three options, lets call them abc, def, xyz. After the user selects and the code does its thing, the output page will present:
"You have selected xyz" for example. Now I want to "transfer" the variable selected to another program which needs the selected option to include a hidden value. The values are:
abc has a value of 300
def has a value of 500
xyz has a value of 900

Remember, the first part does not need this values. They are just need to be included as a hidden in the second form.

How should I do this?

By the way, yes I have "read" most of the manual, including the part on conditional statements. But I am not a programmer, and are just learning how this works. Your help will be appreciated.
Thanks 🙂

Try this ...

<FORM ACTION="<?=$PHP_SELF; ?>" METHOD="post">
<SELECT NAME="select_form">
<OPTION VALUE="abc">abc</OPTION>
<OPTION VALUE="def">def</OPTION>
<OPTION VALUE="xyz">xyz</OPTION>
<INPUT TYPE=submit>
</SELECT>
</FORM>
<P>
<?
if ($select_form) {
echo "<FORM ACTION=\"whatever\" METHOD=\"post\">";
echo "<INPUT TYPE=hidden NAME=\"select_value\">";
echo "You have chosen $select_form";
echo "<INPUT TYPE=submit>";
echo "</FORM>";
}

Thanks!
Here's the thing. I am working with a whois script, mwhois.php. The list of available domain name extensions is generated by calling on a config file. In the config file the extensions are placed in an array. Can I include the "values" in this array? Here's the code:

/* this a list of the whois extensions to use, edit them as you need them */
$whois_exts = array(
	"com",
	"net",
	"org",
);

The first form itself just get the array from this file. The program then "converts" the selection and inserts it in the output page. If teh domain is available, the output page creates a form with the "dmain name"."ext" allready in it. Want I want is to add a <input type=hidden...> to this form...but it has to show the corresponding value for the ext. com = 1000 net = 2000 org = 3000

I tried this in the output page, but it does not work:

<?php
{
if ($ext("") == "com") $gtld = '1000';
}elseif{ ($ext("") == "net") $gtld = '2000';
}elseif{ ($ext("") == "org") $gtld = '3000';
}
?>

<form action="secure_ordering.php" method="POST">
<input type=hidden name=domain value="domains.com">
<input type=hidden name=gtld value=" ".$gtld." >
<INPUT TYPE=SUBMIT NAME="add" VALUE="Registrar">
</form>

If it does not make any sense to you, sorry, I'm doing the best I can 🙂

Try extracting the file extension like this ...

$domain = "whatever.com";
$ext = substr($domain, -3);

Then do your if()

if ($ext == "com") {
do something
} elseif ($ext == "net") {
do something else
}

etc.

Sorry, I didn't mean file extension, I mean TLD. Replace my variable ($ext) with your variable ($gtld).

cheo

I can extract the extension, using the script's own string [>EXT<], but can not get it to include it in the hidden. here's what I did:

<form action="<some secure ordering server>" method="POST">
<input type=hidden name=domain value="[>DOMAIN<].[>EXT<]">
<?php
$ext = [>EXT<]

if($ext == "com"){
$gtld = '1000';
}elseif($ext == "net"){
$gtld = '2000';
}elseif($ext == "org"){
$gtld = '3000';
}elseif($ext == "biz"){
$gtld = '4000';
}elseif($ext== "info"){
$gtld = '5000';
}elseif($ext == "us"){
$gtld = '6000';
}
echo "<INPUT TYPE=hidden NAME=\"gtld\" value=\"$gtld\">";
?>
<INPUT TYPE=SUBMIT NAME="add" VALUE="Registrar">
</form>

Maybe i am placing the if in the incorrect place, as this is the output you get from the whois script. It is really a template for the script. Can this be the problem?

theeper

If your $ext variable actually contains "com" or "net" or whatever, the example you posted will work.

Testing it this way works for me.

<?php
$ext = "com";

if($ext == "com"){
$gtld = '1000';
}elseif($ext == "net"){
$gtld = '2000';
}elseif($ext == "org"){
$gtld = '3000';
}elseif($ext == "biz"){
$gtld = '4000';
}elseif($ext== "info"){
$gtld = '5000';
}elseif($ext == "us"){
$gtld = '6000';
}
echo "<INPUT TYPE=hidden NAME=\"gtld\" value=\"$gtld\">";
?>

Not sure how you are extracting the TLD though.

cheo

I have it set that same way, but is does not work. I am testing the script here http://www.embelecos.com/registrador/mwhois/mwhois.php . It is in Spanish, but don' worry. Just enter a domain name in the box and choose and extension. Then click on "Comprobar" to check it. The page you are going to be directed to is the one in question.

The extension is "extracted" from a tag provided in the script. The tag is [>EXT<], well it is really a "placeholder" for the output. That's were I get the extension from.

Maybe I need to find "a place" in the main script to add the if statement to. I'll keep on trying.

Hey, theeper, thanks a lot for your help!!!!!!!!!!

theeper

hmm, I looked at that link and it seems to be working. I can see the hidden value for the TLD. Maybe you have fixed it by now, or is it still not working?

cheo

I do get the hidden fot the tld, but the other variable $gtld, does not seem to work. If you hit "Registrar" in the answer page, it will post to a form which prints the output. I get the domainname.ext pair with no problem, just can not get the gtld value. I'm almost giving up, thanks for your time.

theeper

So, you are getting a value for the $ext value, and you have checked it and verified that it does contain only "com" or "net" or whatever and no extra characters ?

Seems to me like that is where the problem is. The if() statements look ok, although you may wanna use a switch there, something like this ...

switch ($ext) {
case "com":
$gtld = "1000";
break;
case "net":
$gtld = "2000";
break;

etc...

}

cheo

If switch is used, will the $ext have a value? I mean com, net, org? I am not familiar with the switch funtion.

theeper

Yes, the switch is nothing more that an easier way to write a bunch of ifs and elseifs, although it works a bit differently. Using switch will not affect the rest of your code.

THANKS!! 🙂 I'll look into it and try to use it. Appreciate your help.
