[PHP] Variable value doesn't stay "Null"
I put up an HTML page that allows a user to modify some previously entered information. The information is taken from a MySQL database and displayed on the page. The user can leave the data alone or modify it. If there is no information in the database for one of the fields, the input box is empty. The problem is that when I submit this information, the page that is called does not receive the variables from fields with no information as "null". Instead, it gets them with something other than null, although if I print the variable, they come out blank. I check the variable using "is_null" and they evaluate as not being null. When my script then enters the information into the MySQL database, a value of "0" is entered for the numeric fields. Having these "0" values in the database gives me the wrong information. Any idea why an input field that is populated with a null value would go to the next page as a not null value (although no value shows up for it until it is written to the database)? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
RE: [PHP] Variable value doesn't stay "Null"
So how do I get the PHP script that stores the information in the My SQL database to not store "0"? a "0" value is a valid value for this variable. I don't want 0 to be the value of the variable if nothing is entered. Right now, the database is populated with 0's for the fields that are not filled in. -Original Message- From: Chris Lee [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 15, 2001 8:17 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] Variable value doesn't stay "Null" null is a bad idea. if a value is set to null in a table then that variable will not be set. namephonefaxemail chris lee37710955541120NULL $result['name'] is 'chris lee' $result['phone'] is '3771095'; $result['fax'] is '5541120'; $result['email'] is an undefined variable in php a variable is set or not set. if it set to '' its still set, if a variable is undefined, then it is null. -- Chris Lee [EMAIL PROTECTED] "Michael Conley" <[EMAIL PROTECTED]> wrote in message 2102328FD2ECD411879E00609737BFD10333E3@FATBOY">news:2102328FD2ECD411879E00609737BFD10333E3@FATBOY...

[PHP] File Transfer over HTTPS
I have an Apache Web server running on a Linux server with OpenSSL and all that good stuff. The HTTPS works just fine. Now, many software companies would like to add new features into their software so that their application (written in VB, C and who knows what other languages) can create a text file dump of their information and transfer the file to us over a secure connection. They (the software companies) don't want to have their application interface with a browser as they don't know what browser their customer uses and don't want to deal with the differences between them. Bottom line- Is there a way that an application (not browser-based) can transfer a file to my web server over HTTPS without going through the browser? Can they just open a connection on port 443 and transfer? Where does the encryption happen? I have this happening easily through a browser via a PHP script, but now I need to figure out how to do it without the browser interface.

[PHP] fsockopen question
I am looking to process credit card transactions on my site. In order to do this, I need to open a socket to a particular URL. I then submit an XML string to them. They process the string and send me a response. I am going to a certain (secure) location on the site of my credit card processor (https://www.myprovider.com/XMLSubmit/processtrans.asp) and then submit the XML string. After I submit all of the XML, the processor will give me a response as to whether or not the transaction is approved. How do I send the XML string to the above URL? When I use fsockopen, it doesn't like anything other than an IP address or a host name (ie www.myprovider.com). I don't even really see where to force this to go over HTTPS. I set the port to 443, but need to be sure that the data going across uses SSL.

RE: [PHP] fsockopen question
It looks like that is working, but I'm not getting a response. I created
the XML string and set it as $xmlstring. Then, after the fputs that you
provided below (except with the URL I'm sending to) I have:
fputs($fp, "$xmlstring");
Then, to receive the response I enter:
$RetValue=fgets($w_socket, 4096);
echo $RetValue;
I am not getting any response, so I have no idea if my XML string is
accepted, rejected or what. Is this the right way for me to get the
response? After I send the XML string, they will send me back some info
that will let me know if the transaction is accepted.

[PHP] XML Parsing
I am posting information to a credit card processing server. This is done over HTTPS (with cURL) and seems to work fine. I get the response that I want from the server, which consists of an XML doc with about 20 tags and their corresponding values. I have gone through the mailing list and manuals, yet I still can't seem to figure out how to get each piece of the XML doc into their own variables. Here is the code I am using: $server = "https://www.creditcard.com";; $path = "xmlhttps/xtrans.asp"; $ch = curl_init(); $requestedurl = "$server" . "/$path"; curl_setopt($ch, CURLOPT_URL, "$requestedurl"); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, "$xmlstring"); curl_setopt($ch, CURLOPT_RETURNTRANSFER,0); curl_close ($ch); This replies (as it should) with an XML doc like this: CCDEBITAUTH1010PC-12347512341202MichaelConleyPO BOX 59AuburnCA95604USASomebody840 1003509KQEGVHMGED4172823043020011NO MATCHVITAL6N0 What I need to do now is get certain parts of the return string. How do I assign the value in the tags to the variable $approvalcode? I also need to get several other parts of the XML string assigned to variables so that I can use them elsewhere. I can't seem to figure out how to do this. I know that I need to change the "CURLOPT_RETURNTRANSFER" to "1" to allow the information to be placed somewhere other than the screen for processing, but after that I am not sure how to do this. I have gone through the mailing lists and through the docs online, but I'm having no luck.

[PHP] Incoming XML request
I want to set up a page that can accept an XML string, which I will then parse for the data I need, perform a database lookup based on that data and return an XML string to the client. I am unsure of where to start this. 1. I don't know how to have my PHP page capture the XML string they send me. This will be an automated system, so my web server needs to be ready to accept their XML string. 2. If I can take the XML string from #1 and assign it to a variable, I can extract the information I need. 3. If I can do #1 and #2, I can do the database lookups that I need. 4. How do I send them the results of my lookups in XML? I am running PHP4.04pl1 on RedHat 7.1 and Apache 1.3.14.

[PHP] Using PHP Variables with a Header
I have a form that requires a user to enter various information (name, address, phone number, etc...). When they submit this form, the next PHP page checks to make sure that the required fields were filled in. What I would like to do is check to see if the required fields are all filled in and if they are not, save the values they submitted and go back to the original page, display a message that says the fields that need to be filled in and populate the rest of the fields with the information the user orignally submitted. This will keep them from having to type in all of the information again. I can run the checks just fine to see if the required fields are all filled in. I then save the data from all the fields into variables. What I would like to do is automatically forward the user back to the original page with the values (i already have all of the fields set with "value="$variablename"" to allow them to get the data that is sent back). The only way I have been able to get this to work is to set this up as a regular form with hidden HTML fields and a Submit button. I really want this to be an automatic process. Any thoughts on how to accomplish this? When I set up a "Header", the user is forwarded back to the page that I want, but none of the variables go with them (they are set by simply putting something like "$savedlastname = $lastname, where $lastname is the HTML variable from the original form).
