PHP - If ,else And Else If Statements Using Or
Hi Guys,
Newbie trying to understand PHP conditionals. In the below Code: [Select] [[*id]] is a global variable which equates to my current page id so it could have the value of 1 for example. I tested it using echo and the correct values pass to it in the cms I'm using. What I cant achieve is for the conditionals below to work correctly so perhaps you can see a syntax error or show me away of doing the same using an array or something perhaps? THANKS Code: [Select] <?php $id='[[*id]]' if ($id=="1" || $id=="2") echo "we are in 1 or 2"; elseif ($id=="3" || $id=="4") echo "we are in 3 or 4"; else echo "not in 1 to 4"; ?> Similar TutorialsHey Guys, I am creating an array and I have a need to put a if statement inside it. Is this even possible? Here is where I am at so far, its just not working. function load_permissions($gid) { $data = array(); $this->db->select('`groups`.`name` AS `permission_name`, `permissions`.``'); $query = $this->db->get('`groups`,`permissions`'); if ($query->num_rows() > 0){ foreach ($query->result_array() as $row){ $data[] = array( "name" => $row['permission_name'], "read" => if($row['level'] >= 1) { img("img/true.gif") } else { img("img/false.gif") }, ); } } $query->free_result(); return $data; Thanks, Peter Anything wrong with this because I got a parse error ONLY after adding to create this. <?php $visible = array('Yes', 'No'); foreach($visible as $visible): $visible2 = array('yes', 'no'); foreach($visible2 as $visible2): ?> How to write 2 "if" statements together? if($userResult==$myResult) and ($userResult<0) { Hey guys, is there any way to have a LIKE condition on an IF statement? Something like: Code: [Select] if $GET_['WTV'] LIKE %LOVE% { $category=romance Any clues? Thanks in advance. Hello, I am learning PDO SQL statements, I have mananged to connect using PDO: Code: [Select] try { $this->link = $dbh = new PDO('mysql:host='.$this->dbhost.';dbname='.$this->dbname.'', $this->dbuser, $this->dbpass); } catch (PDOException $e) { echo 'Connection failed: ' . $e->getMessage(); } I am not getting any error, so I guess that is a good start. I then tried the PDO SQL statement out. My old mySQL query is commented out in the Code: [Select] if (isset($_SESSION['id']) && isset($_SESSION['password'])) { $_SESSION['id'] = ( isset( $_SESSION['id'] ) ) ? $_SESSION['id'] : FALSE; $_SESSION['password'] = ( isset( $_SESSION['password'] ) ) ? $_SESSION['password'] : FALSE; //$logged = mysql_query("SELECT * FROM `db_members` WHERE `id`='".$_SESSION['id']."' AND `password` = '".$_SESSION['password']."'"); //$logged = mysql_fetch_array( $logged ); // the new pdo statement $ff = $dbh->prepare('SELECT * FROM db_members WHERE id = '.$_SESSION['id'].' AND password = '.$_SESSION['password'].''); $ff->execute(); $logged = $ff->fetchAll(); echo $logged['username']; } I am trying to assign the session to logged variable. So all I am asking is go into db_members and check the id and password that is the same as session id and password and collect the rows data such as username. My login script and everything works perfectly, even session id and password is valid when echo'd but I cannot assign it to the logged variable like my old sql statements. Code: [Select] $logged = mysql_query("SELECT * FROM `db_members` WHERE `id`='".$_SESSION['id']."' AND `password` = '".$_SESSION['password']."'"); $logged = mysql_fetch_array( $logged ); I used other PDO statements and it works perfectly but I just don't understand why this is not working.... can I please get some help if you have any solution to this? I am trying to write an if statement that checks to make sure the information put in the text box is an imbedded file. Does anyone know how to do that? The below is constantly loading the password page no matter what is enter in the password input on the form (on another page). I have checked the $login variable by echoing it and it is carrying the value from the field. <?php $off="yes"; $login=$_POST['login']; if($off=="yes" && (!isset($_SESSION['login']) || $_SESSION['login']!="pass")){ if($login=="" || $_SESSION['login']!="pass"){ header('Location: ./index2.html'); exit(); } elseif(!isset($_SESSION['login'])){ session_start(); $_SESSION['login']=$login; header('Location: ./index.php'); exit(); } } elseif($off=="no" || $_SESSION['login']=="pass"){ content goes here. } ?> If my SQL statement returns a result I want to change the background color of a cell. If the user is logged in I want to then show one of two buttons. either book, or cancel, depending on whether the cell is available or not. So far I have this: $sql = "SELECT * FROM diary WHERE day = '$mon' AND studio_id ='mon11'"; $query = mysql_query($sql) or die (mysql_error()); if (mysql_num_rows($query) < 1) { $bgcolour= '#5DFC0A'; if(isSet($_SESSION['logged'])) { $book = '<form action="../book.php" method="POST"><input type="hidden" name="day" value='.$mon.' type="text"/><input type="hidden" name="month" value='.$month.' type="text"/><input type="hidden" name="year" value='.$year.' type="text"/><input type="hidden" name="book_id" value="mon11" type="text"/><input type="submit" name="submit" value="Book!"></form>'; }} else { $bgcolour= '#FF0000'; } if(isSet($_SESSION['logged'])) { $book = '<form action="../cancel.php" method="POST"><input type="hidden" name="day" value='.$mon.' type="text"/><input type="hidden" name="month" value='.$month.' type="text"/><input type="hidden" name="year" value='.$year.' type="text"/><input type="hidden" name="book_id" value="mon11" type="text"/><input type="submit" name="submit" value="Cancel!"></form>'; } echo "<td rowspan='3' bgcolor=".$bgcolour.">"; if (isset($book)) { echo $book; } I want to use the $session(logged) variable to show the appropriate button, but I can't get it to work in the other if statement, Any ideas? i have been trying to make this work for days, this needs to also include a discount for staying over >=5 days in Tokyo, no matter what i do i always gets syntax error this class is making me crazy how do i go about getting the discount in this????? please help <?php $destination = $_POST['destination']; $numTravelers = $_POST['numTravelers']; $numNights = $_POST['numNights']; $airFare = $_POST['airFare']; $hotel = $_POST['hotel']; if ($destination == Barcelona) {$airFare = 875.00; $perNight = 85.00;} elseif ($destination == Cairo) {$airFare= 950.00; $perNight = 98.00;} elseif ($destination == Rome) {$airFare = 875.00; $perNight = 110.00;} elseif ($destination == Santiago) {$airFare = 820.00; $perNight = 85.00;} elseif ($destination == Tokyo) {$airFare = 1575.00; $perNight = 240.00;} this is where i can not figure out how to put in the discount off the airfare for staying over five days elseif ($destination == Tokyo && $numNights >=5) $tickets = $numTravelers * $airFare; $hotel = $numTravelers * $numNights * $perNight; $totalCost = $tickets + $hotel; print("<p>Destination: $destination<br />"); print("Number of people: $numTravelers<br />"); print("Number of nights: $numNights<br />"); print("Airline Tickets: $".number_format($tickets, 2)."<br />"); print("Hotel Charges: $".number_format($hotel, 2)."</p>"); print("<p><strong>TOTAL COST: $".number_format($totalCost, 2)."</strong></p>"); ?> Hi, What is a shorter way instead of having all these if statements? Here it is: Code: [Select] if($matchno==1) return 66; elseif($matchno==2) return 67; elseif($matchno==3) return 68; elseif($matchno==4) return 69; elseif($matchno==5) return 70; elseif($matchno==6) return 71; elseif($matchno==7) return 72; elseif($matchno==8) return 73; elseif($matchno==9) return 74; elseif($matchno==10) return 75; elseif($matchno==11) return 76; elseif($matchno==12) return 77; elseif($matchno==13) return 78; elseif($matchno==14) return 79; elseif($matchno==15) return 80; elseif($matchno==16) return 81; elseif($matchno==17) return 82; elseif($matchno==18) return 83; elseif($matchno==19) return 84; elseif($matchno==20) return 85; elseif($matchno==21) return 86; elseif($matchno==22) return 87; elseif($matchno==23) return 88; elseif($matchno==24) return 89; elseif($matchno==25) return 90; elseif($matchno==26) return 91; elseif($matchno==27) return 92; elseif($matchno==28) return 93; elseif($matchno==29) return 94; elseif($matchno==30) return 95; elseif($matchno==31) return 96; elseif($matchno==32) return 97; someone please code shorter? I will learn this way. Thanks. Hello, I'm currently working on just a quick little frontend for VirtualBox and I'm just running into a little bit of a problem that I can't find my way around. Now this is my first project in php. I'm familiar with programming concepts (well except this one apparently ) and by familiar were talking I like to tinker with small languages.. no formal training. Anyway, here we go. So heres the main page. Pretty simple, you type the argument that goes with the following command and check the box next to the command you'd like to execute.

Well, number one I guess is there a more efficient way of doing this that I'm overlooking? I looked into switches but I don't know how I'd pull that off with checkboxes without some complicated loop and somehow converting the checkboxes "yes" or "nos" into numbers or something. If statements just seemed like less of a headache but I may be finding otherwise haha. Number two here is how do I get the "controlvm" command to work? When I comment out that last indented lines of if statements the program runs perfect (and thats with the controlvm function as well. so.. the problem isn't there). Basically whats the appropriate way to do this. I'm stuck and my limited program knowledge and Google searching is starting to run thin. Thanks in advance for the help! Hi There, Im trying to figure out how to do this if/else statement. I need it to say, "if this is true, do this. if this is true, do this. If neither is true, do this. So there are three different possible outcomes.

My arguments: $this->_table = "testdata"; $this->_fields = array('product_id', 'store_id', 'description', 'price', 'colors', 'sizes'); $this->_values = array("20002157", "2005", "Kids polo shirt", "12.59", "White", "Large"); My object: $_crud = new Crud(); $_makeCrud = $_crud->dbInsert($this->_table, $this->_fields, $this->_values); My class: public function dbInsert($table, $fields, $values) { $_table = $table; $_fields = implode(", ", $fields); // Create and format the list of insert values $_values = ""; // replaces values with "?" placeholders foreach ($values as $value) { $_values .= "?" .

My website shows items listed from the database with a picture and associated information including a icon to make the purchase. I want to show the item as sold after the purchase and not the hidden info that is sent to aPayapl to make the purchase. I would like show the item as sold and attach a sold icon but eliminate the paypal hidden info. I tried but when I run the program it breaks. I tried to comment out the stuff i tried. I need some help please. Thanks in advance for any help. Edited August 27, 2019 by vet911Okay i'm trying to compare these sets of variables. code looks like this.. Code: [Select] if( $row->cash > $finalcash && $row->core1 > $finalcore1 && $row->core2 > $finalcore2 && $row->core3 > $finalcore3 && $row->core4 > $finalcore4 ) { return true; } else { return false; } First question is this the appropriate way of doing this? Or would a nested if statement work better? example: Code: [Select] if ($row->cash > $finalcash) { if ($row->core1 > $finalcore1) { if ($row->core2 > $finalcore2) { if ($row->core3 > $finalcore3) { if ($row->core4 > $finalcore4) { } else { return false; } } else { return false; } } else { return false; } } else { return false; } } else { return false; } I know it looks pretty messy, so i'm wondering if anybody is aware of an alternative to achieving this? I'm sure you can do this in PHP, but for some reason when I view news.php - It automatically tells me I liked the post, when I haven't even clicked like yet! while($fetch = mysql_fetch_assoc($query)) { if($_GET['like'] == $fetch['id']) { $like = mysql_real_escape_string($_GET['like']); $has_liked = mysql_query("SELECT * FROM likes WHERE id = '$like' AND username = '". $_SESSION['user'] ."'"); if(mysql_num_rows($has_liked) > 0) { echo " <div id='post-1' class='post'> <h2 class='title'><font color='white'>#". $i."

I can do this using a while loop and insert queries in the loop but its slow and ive been given to understand its a bad idea. I have heard that I can insert multiple rows with one query, but how to construct the query? This code can perfectly and reliably display a statement with echo: Code: [Select] <?php $querytestquery='"INSERT INTO test(qval1, qval2) VALUES'; echo $querytestquery; $querymax=10; $querystart=0; while ($querystart<$querymax) { $qval1=1*$querystart; $qval2=2*$querystart; $queryadd="($qval1, $qval2)"; echo $queryadd; if ($querystart<$querymax-1) { echo ','; } $querystart++; } echo '"'; ?> "INSERT INTO test(qval1, qval2) VALUES(0, 0),(1, 2),(2, 4),(3, 6),(4, ,(5, 10),(6, 12),(7, 14),(8, 16),(9, 18)" But I don't understand how to set a variable equal to the displayed query so that I can have php construct the statement based on the values and the number of records I want to update or insert. Alright, I have a random thing going on. Works perfectly fine. This is the code: Code: [Select] <?php include("config.php"); //To change the odds, change the second number in the rand() function. $rand = floor(rand(0,1)); if($rand == 1) { $sql = "SELECT * FROM randomevents WHERE rarity <= '10'"; $result = mysqli_query($cxn, $sql); while ($row = mysqli_fetch_assoc($result)) { $event[] = $row['phrase']; if ($row['type'] == 'gainsp') { $rand = rand(200,500); $sql = "UPDATE members SET starpoints = starpoints+$rand WHERE userid='".$_SESSION['userid']."'"; mysqli_query($cxn, $sql) or die("Query died: updating starpoints"); } } //This will pick a random event and show it $renum = floor(rand(0,count($event))); $eventdisplay = $event[$renum]; } ?> In the database, I have the phrases set as: "You have gained {$rand} starpoints!". How do you make that variable echo out as the $rand I'm generating on this page? It just keeps posting as is. When I went the {$rand} to display as the number I'm generating to set their starpoints to. So I guess how do you hold a variable in the database? Does anyone understand what I'm asking?
