Codes On One Page
I have a page with a form, a statement and a query. This page is called: form.php When a user enters data into the form and presses submit, that data is inserted into a database, and the user is presented with a success message. However, the problem is, whenever I access (form.php?action=add) without pressing submit it also runs the query which inserts blank data into the database. Is there an easy and simple way to stop this from happening, either by adding a checkform or somehow rearranging the codes to work properly? I would like to keep all these codes on one page without calling up anything else. <?php if ($action == add) { echo "Success!"; mysql_query("INSERT INTO database (data) VALUES('$data') "); } ?> <form action="form.php?action=add" method="post"> <input type="text" name="data"> <input type="submit" value="submit"> </form>

Home Link From Navigation Page
I got a code which helps me to create navigational links and only show 4 results per page. Now I want to add a link on each page such that if anyone clicks on that link it takes it to HOME page. I have added <a href="Home.htm"><b><font size="4">Home!!</font></b></a> inside the loop that generates NEXT and PREVIOUS page link but whenever I click on HOME it does nothing at all.

Adding Page Navigation To Record Set
I have gone through the tutorial on php freaks for adding page navigation to records. I am in the middle of integrating the page navigation and have stuck on 2 areas. 1) I have a page which displays a set of records (limited to 6 per page) Below,is the Next and Previous navigation text bUt it is not hyperlinked!!!?? The line of code specifically is: <?php echo("<a href="$PHP_SELF&page=$pageprev">PREV".$limit."[/url] "); - This should be hyper-linked but is not?? I think there could be a problem with the <href bit being AFTER the <?php. I am basing this on the fact that a previous record i made began the hyper-link <href BEFORE the <?php where as before the <?php was added only after : Code:

Automating Page Navigation And Control Transfer
Is there a system available to do the following: consider an app of a few pages: page1.php: form1----->page3.php form2----->page4.php page2.php: form3----->page3.php form4----->page4.php when I am at page3.php, I do not know whether I came there from page1->form1 or page2->form3. I can check for $_SERVER['HTTP_REFERER'] and get an answer. But this example is simple. Let us generailze that I want an app that keeps a track of all the pages the user requested, in the order that they were sent to him. Obviously, it can be written based on sessions. Is there already some popular open source application for this? Also, this brings me to a broader question of page navigation rules. In an app made of 20-50 pages/scripts, life will be hell if there is no systematic approach to transferring control between pages. Is there some kind of structure already made and readily available into which you just plug-in your pages by telling some rules ? E.g. the scheme is something like: $ListOfPages = array( 1=>"Main.php", 2=>"Edit.php", 3->"Add.php", .........., N->"Error.php"); $RuleSet = array( 1=>array("Main.php","Edit.php","allow_edit"), 2=>array("Main.php","Add.php","allow_add"), ................... 3=>array("Main.php","Error.php","my_error_handler") ); The RuleSet is a set of page transfer rules based on evaluation to true of the specified functions, i.e., allow_edit(), allow_add(), my_error_handler() etc. Obviously, form submission is the chief means of control transfer for PHP programs and the use of ?op=add_something in URL's(GET) and <input type=hidden name=op value=add_something> (POST) are a step towards making some kind of structure. So the grand code will look like: $MyGrandAppControllerObj = new GrandAppControllerObj(); $MyGrandAppControllerObj->setPages($ListOfPages); $MyGrandAppControllerObj->setRules($RuleSet); $MyGrandAppControllerObj->Run();

Generating Hex Codes
I have a function here that generates hex codes for the use of inputing them into html for colors. The function works great, my problem is that sometimes the code it generates ends up a 5 digit hex code, which firefox dosn't like. Any suggestions on how I can ensure that each hex value created is two digits? function randColor(){ $r= rand(0,255); $g= rand(0,255); $b= rand(0,255); $rhex = dechex($r); $ghex = dechex($g); $bhex = dechex($b); $color = $rhex . $ghex . $bhex; return $color;}

2 Adsense Codes But Want To Show Only One
I use only one adsense block on my pages. My pages are usually in wdget.php - widget-blue.php form and there are links on them to some articles. However, when a person clicks on article link they go to widget.php?showfulli_etc. etc. and since I implemented one more adsense code in my script when a person goes to the article page. They see the adsense codes which is the regular one (the first one on wdiget-blue.php and the one in the script which is the second one. What I want is I don't want to show the first adblock when my visitor goes to the article page (widget.php?showfulletc.) instead i want to show the which i implemented into the script. I was wondering if there is any script will disable the first one when a visitr goes to the article page and will show only the one which is implmeneted in the script.

Get Http Response Codes
I have a website in php in which I have some kind of portal to external links that come from a database. When a user clicks on a link, "link.php" is called, does some stuff (e.g. adds 1 to the visit-count of that certain page) and then forwards the user with a location-header to the asked page. Now my question: is it possible to get the response-code of that asked page? E.g. when code 404 is returned, I can put that in the database and then it's easy for me to know when a link is broken.

Confirmation Codes For Forms
I know you get CAPTCHA images for forms, to tell humans and bots apart. But the question that I have is whether or not this has to be an image? The method that I am using at the moment (my site is not yet live), is this: - I create a random number between 1 and 10000 - I then md5 this number to create a random md5 hash - I then pull out 6 characters from round about the middle of the hash - I convert these 6 characters to uppercase, and display them; providing an input box in which the user can enter the code. Obviously, after that, if the code is correct, the form executes. If not, it displays an error message.

Online Reference To Mysql_errno() Codes?
I want to do something like this: while(false == ($result = mysql_query($query)) ) { switch(mysql_errno()) { case $fixableError[0]: case $fixableError[1]: /* fix the errors */ break; default: die ("Fatal error in '$query': " . mysql_error() ); break; } } But I haven't found a satisfactory reference to the error codes. My googling has returned tonnes of references to files in the PHP source, but I'm not willing to download the source files and I doubt that they'd have the kind of error descriptions that would be useful (like, suggestions on how to avoid the error). So can someone supply an address to a reference list of these error numbers? Also, would the syntax in the "while" clause above work in PHP?
