List box and values within functions

Anon

How can I save the values from a drop down menu and show the item that was selected, when the user submits the form as $php_self?
I'm trying to do this within a function and I'm having problems because I'm dynamically creating the options and don't know how to globally declare the values. When the form is submitted the list box only shows the first option(Not Selected) regardless of which option the user selected. I know my code is all wrong, but I'm not sure what to do. I have included a portion of my code below:

function ShowForm()
{
global $PHP_SELF,$resubmit,$article_no,$numberarticles;

print"<FORM ACTION='$PHP_SELF' method='post'>";
print"<Select name='$resubmit'>
<Option value='$article_no[0]'>Not Selected</Option>";

for($i = 1; $i<=$numberarticles;$i++)
{

print"<Option value='$article_no[$i]'>Article No.$article_no[$i]</Option>";

           }
        print"</select>

</form>";
}

Can anyone help?

Thank-you.

Hi,
I am working on exactly the same problem right now.
I solved it like this: I pass the ID of the selected option to the form. Then when I build the drop-down boxes again, I add the option to check wether an option has been set.

code:

if ($Input==1) { // This page has been displayed before
if ($AllTheme==0)
{ // A theme has been slected
$ThemSelectedQuery = mysql_query("select Themes from theme where theme.id = $Them"); //$them is the ID passed from the form
while($row = mysql_fetch_Array($ThemSelectedQuery)) {
$ThemeOptions .= "<Option selected value='$Them'>$row[Themes]" ;
}
}
}

Hope this makes sense. There must be a better method to do this. So if anybody has a better solution.. Please share your ideas!

Hi,

Try this code:

<body>

<?php

function ShowForm()
{
global $PHP_SELF,$resubmit, $article_no, $article_text, $numberarticles;

$numberarticles = 3;

for($i = 1; $i<=3;$i++) {
$article_no[$i] = $i;
$article_text[$i] = "Article " ."$i";
}

printf("<FORM ACTION='$PHP_SELF' method='post'>");
printf("<Select name=\"resubmit\">");

printf("<option value=\"-1\">Not Selected</option>");
for($i = 1; $i<=$numberarticles;$i++) {
print"<Option value='$article_no[$i]'>$article_text[$i]</Option>";
}

print"</select><br>";
printf("<input type=submit value=\"OK\">");
printf("</form>");
}

if ($resubmit < 1) {
showform();
}
else {
printf("You chose %s.<br>", $resubmit);
}

?>
</body
