PHP - Why Won't My If Statements Work?
Todays date is between the criteria in if else, but it is not catching it.
Code: [Select] <?PHP $today = date('Y-m-d'); $sunday = date('Y-m-d', strtotime('last Sunday', strtotime('last Saturday'))); $saturday = date('Y-m-d', strtotime('last Saturday')); $firstday = date('Y-m-d', strtotime('next Sunday', strtotime('last Friday', strtotime('first day of last month')))); $lastday = date('Y-m-d', strtotime('next Saturday', strtotime('last Friday', strtotime('first day of this month')))); $thisfirstday = date('Y-m-d', strtotime('next Sunday', strtotime('last Friday', strtotime('first day of this month')))); $thislastday = date('Y-m-d', strtotime('next Saturday', strtotime('last Friday', strtotime('first day of next month')))); echo"$today<hr />$firstday<br />$lastday<hr />$thisfirstday<br />$thislastday"; if($firstday>="$today" && $lastday<="$today") { $month = date('m', strtotime('-10 days', strtotime('next Saturday', strtotime('last Friday', strtotime('first day of this month'))))); $year = date('Y', strtotime('-10 days', strtotime('next Saturday', strtotime('last Friday', strtotime('first day of this month'))))); echo"1<br />$month|$year"; } elseif($thisfirstday>="$today" && $thislastday<="$today") { $month = date('m', strtotime('-10 days', strtotime('next Saturday', strtotime('last Friday', strtotime('first day of next month'))))); $year = date('Y', strtotime('-10 days', strtotime('next Saturday', strtotime('last Friday', strtotime('first day of next month'))))); echo"3<br />$month|$year"; } ?> output: Code: [Select] 2011-10-10<hr />2011-08-28<br />2011-10-01<hr />2011-10-02<br />2011-10-29 Similar TutorialsThe first piece of code, "screenshot_1", works perfectly but of course is open to SQL injection. If I use prepared statements as per "screenshot_2", and change $result from $con->query($query) to $result= $query->execute()it doesn't work and gives the error, "Fatal error: Uncaught Error: Call to a member function fetch() on bool ". I have read somewhere that this is caused because the 'Select' statement has failed.I am amazed that three lines of code (copied from a php manual) has caused the whole issue to fail.

How to write 2 "if" statements together? if($userResult==$myResult) and ($userResult<0) { 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" || $_SESSION['login']=="pass"){ content goes here. } ?> I am trying to write an if statement that checks to make sure the information put in the text box is an imbedded file. Does anyone know how to do that? Hey Guys, I am creating an array and I have a need to put a if statement inside it. Is this even possible? Here is where I am at so far, its just not working. function load_permissions($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 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? 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. 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"; ?> 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): ?> 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.

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! I am trying to dynamically create a form where I pass a table name and it presents me with a table of all the columns (varying number and names of columns) into an HTML table. Both of my queries are working, but for some reason, my nested while statements are not working.

So when i view someones code and they use shorthand, i get confused. Can i get a clear explanation on the example below:
if ( have_posts() ) : while ( have_posts() ) : the_post(); the_content(); endwhile; else: echo "<p>Sorry, no posts matched your criteria.</p>"; endif;I've always been accustomed to using brackets, so i have trouble understanding the above quickly. 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."

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. I can't get these two if, elseif and else statements too work, here is the code: if(empty($this->password)){ $this->errors[] = 'You must enter a password!'; } elseif(!strlen($this->password) >= 6){ $this->errors[] = 'Your password must be longer than 6 characters!'; } if(empty($this->email)){ $this->errors[] = 'You must enter an email address!'; } elseif(!preg_match('/^[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z]{2,4}$/',$this->email)){ $this->errors[] = 'Your password can only contain these characters: a-z, A-Z and 0-9!'; } if(empty($this->confemail)){ $this->errors[] = 'Please confirm your email address!'; } elseif(!$this->confemail == $this->email){ $this->errors[] = 'The email addresses you entered did not match!'; } The if and elseif statements for "email" work just fine but the other 2 doesn't. With the "password" i first want to check if the field is empty, and when it is, it works as it should. But when i for example type "test" too check if the password is longer than 6 characters i don't get any message at all? With the "confemail" i want to first check if the field is empty, and when it is, it works as it should. But when i type in "test@test.com" in both fields to try to compare "confemail" to "email" i still get the "Please confirm your email address!" message? this is working fine : Code: [Select] while($tags=mysql_fetch_array($d_b->sql_answer,MYSQL_ASSOC)){ echo $tags['tag_name'] . "<br/>"; } display : Code: [Select] html css javascript c++ php but when i try to do some sql statements inside like this : Code: [Select] while($tags=mysql_fetch_array($d_b->sql_answer,MYSQL_ASSOC)){ $sql="SELECT * FROM user WHERE user_languages LIKE '% {$tags[tag_name]} %'"; //to apply the $sql $d_b->apply($sql); //number of results $num=$d_b->num_rows(); $sql="UPDATE tags SET tag_folowers={$num}"; $d_b->apply($sql); } it return an error : Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given If my SQL statement returns a result I want to change the background color of a cell.

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 have a general dbInsert class method that accepts three arguments: table, fields, and values - the last two each as an array. I am using a PDO connection and prepared statements to sanitize everything. I am having a problem with the bindParam() function accepting the parameter ID's though... here's my code and the result I am getting, any advice? 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 .= "?" . ", "; } // trims off last comma and space $_values = substr($_values, 0, -2); // checks database connection if (isset($this->_dbh)) { // Create the SQL Query $this->_sql = 'INSERT INTO ' . $_table . ' (' . $_fields . ') VALUES (' . $_values . ')'; // Build the query transaction $this->_dbh->beginTransaction(); // Build the prepared statement $this->_stmt = $this->_dbh->prepare($this->_sql); // Bind the parameters to their properties foreach ($values as $key => $val) { // starts $key at 1 $key = (int) $key + 1; $this->_stmt->bindParam($key, $val); } // Execute the query $this->_stmt->execute(); $this->_affectedRows = $this->_stmt->rowCount(); } } What my new table row should look like: Code: [Select] product_id store_id description price colors sizes ---------------------------------------------------------------------------------------------- 20002157 2005 kids polo shirt 12.59 white large But this is what my new row DOES look like: Code: [Select] product_id store_id description price colors sizes ---------------------------------------------------------------------------------------------- Large 0 Large 0.00 Large Large So it's taking the value of that last $value and inserting it in all the fields, the store_id and price are 0 and 0.00 because of their numeric type... I assume it is a syntax error, missing quotes somewhere, but where? |
