PHP - Is There A Way To Allow Multiple Variables With The Same Name On The Page?
Is there anyway I can like "exit" the variables so i can use the same variable name later in the page?
Similar Tutorialshello, 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 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: 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 $row['payment_type'] exists, I want it to be displayed in parentheses like: (AUTO) I suspect it has to do with my ' characters for the associative array, but I am new with functions so perhaps it is the multiple arguments that are wrong? I have a form with multiple options to fill out (its a admin form) i want to make sure only one of the of the options are set, so im checking if the variable is empty with if ($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
I have a webpage that I am working on that is now in construction mode. The url is: https://localbizseek.com/lbs/index6 The problem is that I want to it to be able to search 2 at the same time in the phpmyadmin database table which is named "places". I also want to be able to get to search all 9 cities for that area. There are a total of 36,000+ cities in the database. However, I want it to be able to search just 2 or 9 specific cities of those cities. Each city has a city_id which is an integer assigned to it in the database Right now it will search only 1 city at a time or it will search every city in the database if I assign the search variable as "" or "0". I don't know what to do on this page to solve it and on the related processing page. Here is the code on the webpage: <form id="main-search-form" method="GET" action="<?= $baseurl; ?>/_searchresults.php" role="search"> <select id="query-input" name="city_id" style="width:28.8%" style="height:69px" required> <option value="">Select Area</option> <option value="3;1">Ches & VB</option> <option value="3">Chesapeake , VA</option> <option value="9">Hampton , VA</option> <option value="10">Newport News , VA</option> <option value="2">Norfolk , VA</option> <option value="12">Poquoson , VA</option> <option value="4">Portsmouth , VA</option> <option value="5">Suffolk , VA</option> <option value="1">Virginia Beach , VA</option> <option value="11">Williamsburg , VA</option> <option value="0">All Active US Cities</option> </select> </form>
You will notice that I have tried "3;1" up under the Ches & VB Select Option but that doesn't work because it will not work that way. I can have it as "3 1" but then it just displays 1 which is VB's information. I've tried everything possible and it won't search both variables. It only will search one. <form id="main-search-form" method="GET" action="<?= $baseurl; ?>/_searchresults.php" role="search"> <select id="query-input" name="city_id" style="width:28.8%" style="height:69px" required> <option value="">Select Area</option> <option value="3,1">Ches & VB</option> <option value="3">Chesapeake , VA</option> <option value="9">Hampton , VA</option> <option value="10">Newport News , VA</option> <option value="2">Norfolk , VA</option> <option value="12">Poquoson , VA</option> <option value="4">Portsmouth , VA</option> <option value="5">Suffolk , VA</option> <option value="1">Virginia Beach , VA</option> <option value="11">Williamsburg , VA</option> <option value="0">All Active US Cities</option> </select>
Here is the final page of code which I'm not sure if this one needs changing but just in case here it is:

Edited April 13, 2019 by requinix please use the Code <> button when posting code. 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! 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. 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)); hello i have built a webpage using tables. i might have done something wrong (except using tables) and now the results are rendered chaotically on the webpage. also here is the attached file. after the 4th article it's all messy i have a solution but that means to insert a php tag inside another php tag, but won't work thankyou 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!! Hi 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 As part of my User Profile, I have a series of open-ended questions that Members can answer, e.g... Quote 1.) Why did you start your own business? 2.) If you could offer one piece of advice to other entrepreneurs, what would it be? : 10.) How do you compete against large corporations? I was leaning towards creating a many-to-many relationship like this... member -||---------0<- answer ->0---------||- question From a database standpoint this works great, HOWEVER, I just realized a big problem... If run this query... Code: [Select] SELECT response FROM answer WHERE member_id = 1; ...then I would get TEN RECORDS back and I don't know of any way to maps those to the 10 Text Boxes on the "My Thoughts" page?! (It would be a real PITA to have to create 10 separate Prepared Queries in PHP - one for each Field - to fill out my page?!) So, is there a way to keep my table structure, but push the 10 records from above into 10 separate variables so I would have something like $response1, $response2,... $response10 ?? Thanks, Debbie Suppose I have two versions of the same website; one American and one Canadian. This site has members with profiles etc. The way my site is written, I think that if someone were to login to their account on, say, the American site, then a session variable would indicate that a user is logged in on the client machine. Now if they visit the "profile" page, for example, or some other members-only page ON THE CANADIAN SITE, and start manipulating data etc., then this would affect the databases for the Canadian site, and everything would get screwed up (actually, I think mysql would just start spitting out errors, but that's not good either). Does anyone have some simple way to deal this this kind of thing? I don't really know exactly how session variables work. Say I have two domains, somepage.com and somepage.ca on the same server/DNS. If a page on somepage.com sets a session variable called $_SESSION['somevar'], and a page on somepage.ca also sets a variable called $_SESSION['somevar'], are the two variables somehow distinct because they are on different domains? Like, if somepage.com sets the variable, then somepage.ca check if the variable is set, what will happen? What if I wanted to set up the two pages in subfolders, like somepage.com/us and somepage.com/ca, how would I deal with distinguish session variables for the two sites? Is one approach (i.e. distinct domains vs subfolders) better than the other? Thanks, Hi All, I'm quite new to this PHP stuff and have been creating a site just for the hell of it really but i have a rather bizarre problem that has been driving me nuts for about a week... I have two drops downs, the first gives a list of teams from a mysql table and then this populates the next drop down with a list of players from the selected team.. so far so good. When I hit the select/submit button to select the player, what should happen is both the "team" and "player" are put into another query which gives the stats on the selected player for all the games that he has played in. however, what actually happens in the Session variable sets the "team" variable to blank. I can see this happening when I use Print_r ($_SESSION); So essentially when I click on either submit button from my drop down forms the other value is being removed from the Session array. Oh, the session is still valid (not being destroyed and replaced with another session). First drop down $query_teams="select Team from $teams"; $team_result=mysql_query($query_teams); $num_team=mysql_numrows($team_result); echo $num_team; print_r ($row_team); $team_count = 0; echo '<form method="post" action="map_selector.php">'; echo "<SELECT name='country'>"; while ($row_team1 = mysql_fetch_assoc($team_result)) { $team_info = $row_team1["Team"]; echo "<OPTION value='$team_info'>$team_info </option>"; } echo '</select>'; echo '<center><input type="submit" value="Search"></center>'; $country = $_POST["country"]; $_SESSION["country"] = $country; echo '</form>'; So SCOTLAND is selected Some sql queries to get the results for the possible players and then Drop down 2 $row_full = array_unique($row_home); echo '<form method="post" action="map_selector.php">'; echo "<SELECT name='Player'>"; foreach ($row_full as $key => $value) { echo "<OPTION value='$value'> $value"; } echo '</select>'; echo "@"; echo $country; echo "@"; echo '<center><input type="submit" value="Search"></center>'; $country=$_POST["country"]; $player=$_POST["Player"]; echo "#"; echo $country; echo "#"; echo '</form>'; $_SESSION["Player"] = $player; $selected_player = $_SESSION["Player"]; echo $player; echo $selected_player; echo $country; Print_r ($_SESSION); so Print_r ($_Session) returns: Array ( [Player] => [country] => Scotland [] => ) then a player "Paul Hartley" is selected from the player list and submit is click and then Print_r($_Session) shows: Array ( [Player] => Paul Hartley [country] => [] => ) Can anyone please help... I just can;t understand why this is happening when I'm using a Sessions which, I thought, would retain all variable values until a time-out or a destroy Thanks nhsal69 Hey guys, Really dumb question, but I want to check if a bunch of variables are all not empty. Then, if they aren't, I want to execute a mySQL query. Right now I have this which I know is wrong because it doesn't work the right way: Code: [Select] if($album != null || $artist != null || $year != null || $genre != null) { // stuff here... } Obviously I want all of those variables to be checked if they are empty or not. I did a quick Google and found that checking if the variables are null wouldn't be the correct way of solving this situation because an "empty string" is still not null? Anyway, any help would be appreciated. I'm pretty sure it's really simple :p. This seems to be a bit of a challenge but I am creating a multiple page form and on one of the pages I have a select field. I would like the user to have the ability to select multiple options but I am using some functions to move the data in hidden fields from page to page. I don't think my functions are jiving with my my foreach loop cause I keep getting an invalid argument error. Thanks in advance for any help. Here is my function: function setSelected($fieldName, $fieldValue) { if(isset($_POST[$fieldName]) && $_POST[$fieldName] == $fieldValue) { echo 'selected="selected"'; } } And here is my loop: $selections = ""; if(isset($_POST["selections"])) { foreach ($_POST["selections"] as $selection) { $selections .= $selection . ", "; } } How would I pass variables from one page to another without using forms or $_GET features. Let say I have page (1.php) where If define $secret_phrase = "open sesame";. On that page (1.php) I have multiple html links to multiple pages (2.php, 3.php, ...) if you click on the link to 2.php page I would like to pass the $secret_phrase as well without having it encoded into a link or using forms. Is there a way to do it? Thanks i have problem : I have a page(page1) that sends details to the login page(page2) to check if the details are correct checks these and if there is a match it directs them to the next page.(page 3) The page1 sends 3 details to the page 2 that are stored into variavles but as there is no submittion when they check the details how do i then send these details onto the page 3 ? |
