hello, im wondering how to properly code the following.
Code: [Select] $stdate = date( 'Ymd', strtotime($pdate) ); $sttime = date( 'His', strtotime($tstart1) ); $dtStart = ".$stdate.'T'.$sttime.'Z'"; echo "$dtStart"; i would like the echo to read 20110309T050000Z Similar TutorialsHi Guys and Girls, Long time lurker, first time poster! I am usually able to read through the forums and find and answer without having to start a new thread but I've tried my best to no avail. I am having trouble with the following code: $afname="Gareth"; $alname="B"; $awayoption.="<OPTION VALUE=\"".$afname." \"".$alname."\">".$afname." ".$alname; I would want that to produce the following: Code: [Select] <OPTION VALUE=Gareth B">Gareth B The actual result at the moment is: Code: [Select] <OPTION VALUE="Gareth "B">Gareth B It has an extra " in the middle. Any ides or help would be great! Cheers Hi I am trying to get all variables passed in a url string and wondered how would i do it? I dont know what they are yet and i need to set key as value. Any help? I have a string that looks like /index.php?g1=111&g2=222&g3=333. How can I obtain the value of g1 (i.e. 111)? It does not represent the current state of the server thus I cannot just use $_GET. It also is not necessarily the first item. The script below appears to work, however, http://php.net/manua...n.parse-url.php states This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards compatibility requirements it makes an exception for the file:// scheme where triple slashes (file:///...) are allowed. For any other scheme this is invalid. It appears that my string is a URI and not a URL, but I might be wrong. How should this be accomplished
<?php
$str='/index.php?g1=111&g2=222&g3=333';
$array=parse_url($str);
parse_str($array['query'],$get);
echo("<p>{$get['g1']}</p>");
?>
$id[] = 12345; $id[] = 12345; $id[] = 12345; $id[] = 12345; $id[] = 12345; how would I combine these into a string "12345,12345,12345,12345,12345" Hi, I have a string with the value of
{ "success": true, "delivered": true, "contactDetailsRequired": false, "message": "Signed For by: D ANDERSON ", "signature": "https://webservices.thedx.co.uk/PodImage/ImageHandler.ashx?tn=906732192165", "date": "21-07-2020", "serviceLevelName": "Consigned", "time": "13:33:19", "trackedProductName": "DataExchange" }
How do i go about placing the values into variables so for example: $success = "true"; $delivered = "true"; $message = "Signed for by: D ANDERSON"; etc.... My mind has gone blank and im having one of those days, any help would be greatly appreciated. Thanks I have the following code which has deliimiters of |||| and I need to break it apart into three strings and have a variable assigned to each string. I've tried exploding it but won't dynamically increase the variable. I know at one point about a year ago I used something like $var.=$foo and the $var would increase $var1, $var2, etc... Here's the string I need to break.j (And the string will be different every time, and some will have 2 string delimited some will have 20, and some inbetween.

It's actually data from a form that I pass to said variable. What I want is to then in turn use this string in a mkdir() function. Something like Code: [Select] mkdir("dir/folder/$ename/"); Obviously that doesn't work. I'd imagine I have to use some sort of . syntax. I have an audit trail that record users ids and a copy of the sql string for any updates they make to my application. This is very easy for me to follow to find exactly where changes happened but do end users it is a bit of a challenge. Has anyone seen or made a script that can either compare two sql strings to see what fields have different values or a script that takes an SQL string and outputs its field names and values to an array that I can use for comparisons? Example being the look at a update made by user X, the database pulls the sql for that change then looks for the previous change up any user before (update sql should have a value for all fields) then compares to see what user X changed. If not im thinking of case statement to divide sql request between inserts and update then writing a script to split the strings based on where the commas were. Any thoughts? Code: [Select] $query = "SELECT content FROM license WHERE serial = '".$serial."'"; I have a form with multiple options to fill out (its a admin form) i want to make sure only one of the of the options are set, so im checking if the variable is empty with if ($variable1 != NULL) { $new_variable = "yep, this option was filled out"; } so if the form sent anything from the form with the value 'variable1' it then sets a new variable ($new_variable) Problem is i have multiple fields so i need to make sure if it finds a a variable is not empty, then too check if the others have anything in them too. If it does find another (meaning more than one has been filled out) echo an error (echo "you must only complete one option..") What is the best way to check if more than one variable exists? Sorry if i explained it complicated. Thank you Hello everyone, I'm sitting here in a position where I can't work on my site or test any code, but my mind is racing about what I can do to solve a particular problem that I have. I won't get into the problem because it would take more time to type than I have right now, but I have an idea for a simple solution, just not sure if it will work or not. So, here's my question: Is it possible to have multiple session variables during a session? Such as: $email=$_SESSION['email']; $user=$_SESSION['userid']; If this is possible, my problem is solved (I think)... otherwise, I have to keep thinking about it. Thanks for any help! I have this function: Code: [Select] function echo_exist($pre1,$ee,$post1) { if ($ee!='') { return $pre1; return $ee; return $post1; } else { //do nothing } } But when I try to echo it Code: [Select] echo_exist("(","$row['payment_type']",")"); I get syntax error, unexpected T_ENCAPSED_AND_WHITESPACE If $row['payment_type'] exists, I want it to be displayed in parentheses like: (AUTO) I suspect it has to do with my ' characters for the associative array, but I am new with functions so perhaps it is the multiple arguments that are wrong? Hi, I'm having a bit of a problem sharing some variables I have across a few files. My first file (index.php) calls an ajax request for (display.php) and sends a few variables to it. All fine so far. display.php then does its thing and displays the content on index.php as it should. Now in display.php I need a variable to be passed back to index.php for use in a menu. I've tried setting a session variable in display.php but unfortunately this doesn't seem to work. I also can't use get or post as I don't want to refresh the page. Really scratching my head over this one! Edd Hi, I want to send the following variable using the $_GET function: Is there anyway I can like "exit" the variables so i can use the same variable name later in the page? I am creating a webpage for my golf league and some of the information(variables) such as Name, Address and email, must be reused across multiple pages for different outputs. May question is "Can I, or is there a way to reUse variables across multiple pages. "Do I need to create a session and make everything session variables"? "Should I link to a database and call the information when needed"? Any explanation would be greatly appreciated. Hi, I have an affiliate system that shows results on what product is purchased. The problem is that the tracker is only listing the first product in the purchase list, so if someone purchases multiple products it only shows the first product in the transaction report. Here is the code: Code: [Select] $module = fetchDbConfig('PostAffiliatePro'); $orderInv = $order->getOrderInv($_GET["cart_order_id"]); print_r($orderInv); $affCode = "<!-- Begin PostAffiliatePro Affiliate Tracker --> <img border='0' src='".$module['URL']."/scripts/sale.php?TotalCost=".sprintf("%.2f", $orderSum['subtotal'])."&OrderID=".$cart_order_id."&ProductID=".$orderInv['0']['productCode']."' width='0' height='0' alt='' /> <!-- End PostAffiliatePro Affiliate Tracker -->"; ?> The code I need help with syntax is: Code: [Select] "&ProductID=".$orderInv['0']['productCode']."The products are split into arrays by number (0,1,2,3). So for example, I would want to show results for .$orderInv['0']['productCode']. , then .$orderInv['1']['productCode']. , and so on. I would like the results to be posted with a ; between them, but I don't know the proper syntax to have it report more than just the first array. This seems pretty simple, but I only know the basics of PHP and I've adapted this from found code. Any guidance would be greatly appreciated. Thanks! When a user logs into my site I was to store the user_name, user_role, and user_id in a session variable, then store this in a regular variable to make querying easier, but I am having issues with my code as its causing issues with my queries. Code: [Select] if (mysqli_num_rows($data) > 0) { //set sessions $row = mysqli_fetch_array($data); $_SESSION['username'] = $row['username']; $_SESSION['user_role'] = $row['role']; $_SESSION['user_id'] = $row['user_id']; //set variables $username = $_SESSION['username']; $user_role = $_SESSION['user_role']; $user_id = $_SESSION['user_id']; } Any ideas whats wrong?! Thanks for the help!! This will only send 1 goggles information into the database but I have a "adding" page that can actually add more than 1 goggles at once. I have no idea how to go about saving multiple goggle's information using array or loop. $name= $_POST['goggles_name']; $price = $_POST['goggles_price']; $des = $_POST['goggles_description']; $file = $_FILES['goggles_image']['name']; $chkbox = $_POST['upload']; $id = $_POST['goggles_id']; $query = "UPDATE goggles SET goggles_name = '$name' , goggles_price = '$price' ,goggles_description = '$des' WHERE goggles_id ='".$id."' "; $result = mysqli_query($link, $query) or die(mysqli_error($link)); |
