| | It seems there is an error in the tutorial you are using. the "@" symbol is actually used to suppress an error that the following function might throw: [url]http://www.tuxradar.com/practicalphp/19/8/12[/url] I'm assuming the author ment that to be a "$" symbol, as that indicates a variable. that line should be [icode][b]$[/b]AcmeInventory … |

 | Holy Moley, you'll hate your self for this :P You forgot a crucial line: [icode]mysql_query($sql);[/icode] which should go on line 16. As your code stands, it doesn't execute the new SQL command, just sets the $sql variable. Regarding the VALUE syntax, VALUE and VALUES are interchangeable. |
| | Re: Syntax Error The problem you are having is with your double quotes. [code=php] echo "value of the constant CONSTANT: " . CONSTANT; [/code] notice the text in blue, this is a string. You are trying to put double quotes inside a string without escaping them. If you place a backslash directly before …  |

(you can use [icode]isset($_POST['delete'])[/icode] to see if they clicked "Delete" but $_POST['delete'] will hold the value "Delete"). … |

| | a variable (such as [icode]$myusername[/icode]) must be set [i]in the same script[/i] for it to have a value, and thus be echo'd to the page. This means the value will be lost if the user refreshes the or follows a link. The [icode]$_SESSION[/icode] is a special array that will hold …  |

| | As PHP is a server side language, PHP can't be used to modify the page once it has been sent to the browser. You need a client side language (that is executed by the viewers browser) such as Javascript to do what you are explaining. I haven't done much with … |
 | Re: Templates in PHP There are functions for including in a script, a script held in another file. Is this what you mean? i.e. you can define the functions that you will use (and constants, variables, etc) and then [URL="http://au2.php.net/include/"]include [/URL]them. Syntax: [code] include 'functions.php'; include "variables.inc"; [/code] See also, [URL="http://au2.php.net/include_once/"]include_once[/URL], [URL="http://au2.php.net/require/"]require [/URL]and [URL="http://au2.php.net/require_once/"]require_once[/URL]. |
| | Ok, you need to look at a few tutorials (there's millions on the net) about user logins and sessions. In a nutshell: [ICODE]form.html[/ICODE] This contains the textbox. [code=html] <form action="submit.php" method="GET"> <!--or "POST"--> <input type="text" name="username" /> </form> [/code] [ICODE]submit.php[/ICODE] Set the session variable [code=php] <?php session_start(); //so you can … |
| | @bappaditya Are you saying "www1" is to www1.example.com as "mail" is to mail.google.com? Does this mean that "www" a subdomain but many modern web servers are able to assume a subdomain of "www" when none is given? (because "www.mail.google.com" doesn't give a response) Thanks for clarification. |
| | first, after $find_ad has been set, I would split the data by [icode]$list = explode("</tr>",$find_ad)[/icode] then do a replacement on each item like so: [code=php] $list=preg_replace("/([^>])(</a> \(\d{4}\))/",'\1\2 - <a href="http://www.theflickzone.com/search.php?do=process&sortby=lastpost&titleonly=true&query=\1"> Search </a>',$list); //then to wrap it up: $new_page = '<table border="1" cellspacing="0" cellpadding="4" style="margin-right:30px;">'; foreach ($list as $item){ $new_page .= …  |
| | To have less of an impact on the server at runtime I'm guessing 2) would be much better as in 1) you must load the entire history of news items into memory as opposed to about 30 bytes per news item. (Have I interpreted you correctly?) |
| | Ok, first off I'd direct my form to a page of my own, say "submit.php", which would store the data passed to it into the database and then (before echoing any data to the page) use header() to redirect the user to the api url. I'm assuming you know ho … |

| | What exactly are you asking for? What is a word "we like"? It will probably be possible to write a function to do what you want but I'm not entirely sure what that is. All in all, what info do you want to get out of the function and what … |
 | I have just written a script to do just that. I used [URL="http://au2.php.net/manual/en/function.ereg.php"]ereg()[/URL] to do a search for a regular expression that will verify a valid entry. e.g: [code=php] if (!ereg('^[0-9][0-9]-[0-9][0-9]-[0-9][0-9][0-9][0-9]$', $date)){ //I got an error when I used "[0-9]{2}" instead of "[0-9][0-9]" //^ matches start of string and $ … |

The domain will be in $4. If you know you have a valid URL and you can assume that the domain is longer then 3 chars then you can use the simpler [icode]"([a-zA-Z0-9-]+)(\.[a-zA-Z]{2,3})+(/|$)"[/icode] which will leave … |
| | Re: Search problems Here's a few mistakes in your code that I have spotted: [code=php] if($gender==all||$sercountry==all){ //should be: if($gender=="all"||$sercountry=="all"){ [/code] Here is how I would structure it: [code=php] <?php include"config.php"; $gender=$_POST['gender']; $sercountry=$_POST['country']; trim($gender); trim($sercountry); if(!$sercountry || !$gender){ //fail echo "<font color=brown><b>You have not entered ALL search details.<b></font>try again</b></font>"; exit; } if($gender=="all" || $sercountry=="all"){ … |

 | [url]http://www.tizag.com/mysqlTutorial/index.php[/url] Have a look through that (there's a lot there so just make sure you get what you need). One thing, with your code: [icode]define ("PAGE_TITLE", "Properties for sale in $record[countryname]");[/icode] You should have: [icode]define ("PAGE_TITLE", "Properties for sale in $record[[COLOR="Red"]'[/COLOR]countryname[COLOR="Red"]'[/COLOR]]");[/icode] That will work if the array $record has an … |

| | Did you actually use "http://xx.xx.xxx.xxx/..." as $fullpath? Because I've got a feeling that wouldn't work. [icode]if (file_exists($fullpath))[/icode] is being used remember, and by the look of it is returning FALSE. Also, [icode]http%3A%2F%2F69.80.208.156/birkeys/phpThumb.php[/icode] is a bad href. As php will see all the characters in the URL as literal anyway, you … |

| | Why the [icode]$result = mysql_query($query);[/icode] on the fourth last line? You don't need the [icode]$result =[/icode] on that line as the mysql_query will return [icode]TRUE[/icode] on success. You are then treating this as a MySQL result resource in [icode]mysql_fetch_array($result)[/icode] (because the expression in the why loop is executed every time … |
| | Re: PHP Tables What buddylee said. What does the source to your page look like? It's probably not correct at all but IE happens to display it correctly.
