Re: [PHP] Drop down list - persistant value
I use a function to create select boxes:
function make_select($fieldname,$options,$selected,$opt=) {
# make a select box with option text $opt
# $fieldname = name of html field
# $options = associative array of select options
# $selected = field key of selected item
# $opt = optional attributes, e.g., styles, etc.
$output.=\nselect name=\$fieldname\ $opt ;
foreach ($options as $key=$val) {
$output.=\noption value=\$key\;
if ($key==$selected) {
$output.= selected;
}
$output.=$val;
}
$output.=\n/select\n;
return $output;
}
By passing the previously selected item as $selected it will
automatically reselect the chosen item. For instance,
?php echo make_select(myfield,$options,$_POST[myfield]) ?
I've written similar functions for check boxes and radio buttons.
They've made form creation and handling enormously easier.

I am using PHP. I have a registration page where the user has to select his
country form a drop down list. If the username that the user selected for
himself exists in the database I am sending him back to the registration
form with all the fields completed with the values he previously entered.
This is easy to do for a textfield but how do I indicate on the drop down
list which country he originally selected?
Please help.

Re: [PHP] protecting downloads with php
It can be tricky to write download wrappers that work with all browsers. Some versions of Internet Explorer seem especially troublesome. I've found wrappers like these seem to work fairly well: initialization(); authorization($user,$pw); $info=get_file_info($filepointer); ### SEND HEADERS ### header(Content-Type: .$info[mimetype]); header(Content-Disposition: inline; filename=.$info[filename]); ### NO TEXT CAN BE ECHOED BEFORE HERE ### ### Open the file and display it $fp=fopen($filepath./.$info[filename],r); fpassthru($fp); fclose($fp); ### END A few observations: PHP will complain if you send any text to the browser before calling header() (since HTTP headers can't be sent once the data segment begins). Sometimes this problem can be hard to track down. I've left invisible whitespace after the closing ? tag in a file included above the calls to the header function(). The PHP parser naturally views this whitespace as HTML content and echoes it to the browser. The filename portion of the second header usually points to the name of the file itself without any leading path component. Some versions of Internet Explorer fail to initiate the download unless a separate window is opened. Most modern *nix systems have a mime.types file. A quick scan of one RedHat Linux 7.1 machine finds the Apache mime.types file stored as /etc/mime.types along with some sample mime.types files installed by applications like lynx and mutt. The file is delimited by white space (usually a tab) between the type and list of extensions making it easy to write a function that converts it into an array $mimetype[$extension]. If you collect inbound files by mail (as I do) or by HTTP upload, you'll find the file's MIME type in the session headers. Since most people's mail or web client runs on the same machine as their application, these headers are usually pretty accurate.

Re: [PHP] php4 on RedHat 7.1
Take a look at /var/log/httpd/error_log. Is there an entry for the very first time the server was run (before you installed PHP 4.04pl)? Does it list PHP/4.0 as installed? The initial entry in my error_log from the Wolverine beta of 7.1 shows: [Fri Apr 27 12:36:13 2001] [notice] Apache/1.3.14 (Unix) (Red-Hat/Linux) mod_ssl/2.7.1 OpenSSL/0.9.5a DAV/1.0.2 PHP/4.0.4pl1 mod_perl/1.24_01 configured -- resuming normal operations [Fri Apr 27 12:36:13 2001] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec) In my case the PHP module was loaded by default (along with ssl and mod_perl) when I chose the install everything option in RedHat. If it appears in the log, then the module is running. Put a file called info.php into /var/www/html with just the line ? phpinfo() ? in it. What happens when you view it from a browser? If it's still not working, I suggest you try uninstalling your version of PHP and installing the PHP4 rpm that comes with RedHat instead. Works fine for me.
