PHP - Is True True?
I am wondering if these "true" values are the same to PHP...
Code: [Select] <a href="' . BASE_URL . 'members/log_in.php?addComment=true">Log In</a> Code: [Select] if (isset($_GET['addComment']) && ($_GET['addComment']==TRUE)){ Debbie Similar Tutorials$looponce = 1; foreach ($this->info as $k => $v) { if ( (($k == 'subject') && ($v['required'])) && (!$this->settings['customSubject'])) { for ($i = 0; $i <= 0; $i++) { $output[] = $this->display_errors('error_system_subject'); } } if ( (($k == 'name') && (!$v['required'])) || ((!array_key_exists("name", $this->info)) && ($looponce == 1)) ) { $output[] = $this->display_errors('error_system_name'); $looponce++; } } That is my loop that i check things in. What i'm more interested in is the name if statement. If currently checks for a name key in an array(below) and makes sure that it is set to required. If it's not set to required, print out a system error and die()'s. I'm looking for ways to remove the need for program errors and just change them to what is needed to run. What i know how to do is, get into the inner array, what i don't know is how to edit the data and put it back exactly as it was given to me. The inner array data can be put back in any order, but the outer array must be in exact order as it was given. above code $this->info = $formdata; $formdata = array( 'name' => array('name'=>"Full Name", 'required'=>false, 'type'=>'text'), # This needs to be required=>true, but i can't trust the user, which is why i have the error. 'telephone' => array('name'=>"Telephone", 'required'=>false, 'type'=>'phone'), ); Any help is greatly appreciated, also am i doing the foreach loop in the code above in an efficient manner or is there another way? Apart from the fact this can cause an infinite loop is it OK to use? $user->reset_token = $user->generate_password(32); // Make sure the token is unique while(TRUE) { $count = ORM::factory('manager')->where('reset_token', '=', $user->reset_token)->count_all(); if($count < 1) break; $user->reset_token = $user->generate_password(32); } Or would you approach the logic for this differently? Thoughts appreciated. Cheers Is there any reason why I would want to use this... Code: [Select] $_SESSION['loggedIn'] = TRUE; versus this... Code: [Select] $_SESSION['loggedIn'] = 1; (The first one is easier to read...) Debbie hi i have set 2 varibles, and want to echo them out if they are true, i have this script but doesnt work, please help. <?php $month=$_GET['month']; $year=$_GET['year']; If($year!=0 && $month!=0) { echo $month; echo $year; } ?> cheers matt Just a silly question. I've been using 1 and 0 to tell if something is true or false, such as if a feature is enabled or not. I see that some use the words true and false. Is there a proper way or is either way correct? Thanks! <?php $id1 = '5' ; $id = array(1,2,3,4,5,6,7); foreach($id as $value){ if($id1==$value){ echo 'One of them matches, ' ; echo 'Do not execute command <BR>' ; } ////// if ends here } ////// loop ends here ?> How to do something if all statements are false ? like when id $id1 = '10' , ? Hi Not that often I play with these (and normally just a single font I use). However I am trying to generate an image with a ttf bit of text on it. No problem using Tuffy.ttf (the normal one I use), but I want to use some arrow characters which it doesn't support. I have tried using Wingding and Webdings but neither work with GD. Am I missing something (hopefully something obvious)? All the best Keith I'm pulling my hair out trying to figure out a simple problem. I've got the following PHP code in an HTML page: $shutoff_date = strtotime($wkend_start_date) - 259200; if ($shutoff_date > $todays_date) { $current_month = date("m"); $current_year = date("y"); $freshman_eligible = 0; if ($current_month >= 2 && $current_month <=7) { $freshman_eligible = 1; } if ($current_month <= 7) { $seniors = $current_year ; } else {$seniors = $current_year + 1; } $juniors = $seniors + 1; $sophomores = $seniors + 2; $freshman = $seniors + 3; echo "HTML Stuff blah, blah, blah"; if ($freshman_eligible = 1) { echo "<option value=\"$freshman\">$freshman</option>";} } The last test to see if $freshman_eligible is equal to 1 is always testing true, and it's actually resetting $freshman_eligible to whatever I put inside the IF statement. No matter what the variable is set to previously, it will reset to whatever I test for in the last section, and hence always tests true. I thought maybe it was an issue with scope, but I'm not sure what the issue would be or how to resolve it. What am I missing??? <?php if('00' == '000') echo 'weired'; ?> Please consider the code above. Strangely it echoes the word "weired". Also if('00' == '000000000000000') returns true and so forth. What is really going on? Thanks in advance By the way the php version is 5.3.9 on wampserver 2.2 Hi, Apologies if this is rather easy but wondered how you would get around the following problem. I have a post being sent on a checked form that has the name set to a value used in my DB, for example: Code: [Select] <input type="checkbox" name="<?PHP echo $rows ["catID"] ?>"> Where name would equal something like 11. I'm trying to right some code that inserts data from the rows that have been checked, bit like the below: Code: [Select] while($rows = $database->fetch_array($result)){ $strSQL='INSERT INTO affiliate_join_cat (ajcCatID, ajcAffID) VALUES ('.$rows["catID"].', '.$_POST["affID"].')'; if ($_POST($rows["catID"])=="on"){ $database->query($strSQL); so my post will look something like 11 = on, dependent on the row checked. But there is something wrong with this part of the code: Code: [Select] $_POST($rows["catID"])=="on" my thoughts are that until catID actually equals 11 this does not evaluate to anything? So have tried using empty and isset to handle it without any success. Not sure what to do next? Thanks in advance Hey here is my code im trying to redirect the index.php to index.php?id=1 the way i have done it doesn't look really good is there a better way to do it please? im trying to redirect to id=1 because otherwise i wont be able to echo out anything... id 1 is default category so is there a way to tell it if $id is empty echo from id 1? <?php $id = $_GET['id']; if($id == ''){ echo "<meta http-equiv=Refresh content=0;url=index.php?id=1>"; } $result = mysql_query("SELECT * FROM pages WHERE id='$id' ",$connect); while($row = mysql_fetch_assoc($result)) { echo $row['anything1']; echo $row['anything2']; } ?> I have a statement $account = $_SESSION['account_id']; $postedby = $account_id; /*both echo out to the same number*/ if($account == $postedby){ echo "DELETE BUTTON"; } i echo'ed out both $account and $postedby and both return 1 but the if statement fails to read as true. HELP!!! thanks in advance! so im trying this
$file is not a .txt file
if ($file != "." && $file != ".." && !is_dir("uploads/$fuser/$file") && (pathinfo("uploads/$fuser/$file", PATHINFO_FILENAME)!= "txt")
i tried this but doesnt work
So in my last thread I was working on checking if a file was there...I resorted to something not in the library and used $pic_exists_jpg = fopen($jpg_path,'r'); $pic_exists_jpeg = fopen($jpeg_path,'r'); $pic_exists_gif = fopen($gif_path,'r'); $pic_exists_png = fopen($png_path,'r'); if ($pic_exists_jpg != '0') { $jpg_test = '1'; } elseif ($pic_exists_jpg == '1') { $jpg_test = '2'; } elseif ($pic_exists_jpg == '0') { $jpg_test = '2'; } elseif ($pic_exists_jpeg != '0') { $jpeg_test = '1'; } elseif ($pic_exists_gif != '0') { $gif_test = '1'; } elseif ($pic_exists_png != '0') { $png_test = '1'; } now for some reason php is being a poo and no matter what returning that there is a file there. no matter what method i use be it fopen or file_exists or anything else, it saying I have a file in that directory BUT I DO NOT! THERE IS NOT ONE OF THOSE FILES. I know I have my paths right because If I echo them directly I get the picture...what the heck?! i keep seeing people use this kind of code but i cant find any document or help web pages on it. im sure there is but i done know what to call it. i would really like to learn more about it for example Code: [Select] $lang = isset($_GET['lang']) ? (int)$_GET['lang'] : 1; or Code: [Select] return !empty($result_array) ? array_shift($result_array) : false; Dear PHP Experts,
I have one simple question to ask you that i have to redirect an entire site into new domain using 301 Redirect In Htaccess. Also i have to check one condition.
I have variable called $country; It stores country name, I have to redirect only if the country become "INDIA"
Im confused that my condition is comes in my php file & 301 redirect is in htaccess. How its possible ?
Thanks IN Advance

I had some code that I'm pretty sure used to work, basically something like the below. Code: [Select] if (preg_match("/[a-zA-Z0-9]+/", $_POST['title'])) { echo $_POST['title'];exit(); } Now i just don't get why it always returns true, even when entering special characters like "!#%?".. The only thing which comes to mind, is that i recently made a move to UTF-8.. Hello Was wanting you know if anyone had come across a method whereby the following occurs: On editing an existing record pulled back on a form, if a checkbox is change to TRUE (ticked) and then the record is submitted to update the database, then it should also record the date/time in a particular field e.g. 'checkboxupdate'. I already have a general update time/date field but this is updated whenever a record is updated. I want the new 'checkboxupdate' field to only be updated with the date/time when the submission includes the change to write TRUE to the checkbox field. As an aside I would need to ensure that the checkbox is read only if the value pulled back from the recordset is true........ Hope this makes sense. Thanks Demetri I am trying to take all the information from $results and input it into a text file, sometimes we get duplicates in $results so I want to check the text file for the entry before writing it in so we don't get duplicates in the text file. However inarray keeps returning false, even when I echo out the two arrays and they match? Code: [Select] $myfile = "complete.txt"; foreach ($results['info'] as $data) { $output=$fields['firstname']."|".$record['lastname']."|".$record['address']."|".$record['number']."\n"; $handle = fopen($myfile, "r"); $contents = fread($handle, filesize($myfile)); fclose($handle); $list = array(); $list = explode("\n",$contents); $list = array_map("trim", $list); $current = $output; echo in_array($current,$list) ? $current.' exists' : $current.' does not exist'; if (in_array($current,$list)) { print "duplicate"; } else { if($file=fopen($myfile, "a")) { //open file for writing fwrite($file, $output); //write to file } } } I have an IF statement that is constantly returning TRUE, even when it shouldn't be. Basically it checks if an array is empty. Code: [Select] <?php $error = array(); //No blanks if ($street_addr == "" || $city == "" || $state == "" || $zip == "" || $phone1 == "" || $phone2 == "" || $phone3 == "" || $county == "") $error[] = "You left something blank!"; //validate zip if(!preg_match("/^[0-9]{5}$/", $zip)) $error[] = "The ZIP code must be a 5-digit number."; //validate phone number if (!is_numeric($phone1) || !is_numeric($phone2) || !is_numeric($phone3)) $error[] = "Phone can only contain digits"; if (strlen($phone1) < 3 || strlen($phone2) < 3 || strlen($phone3) < 4) $error[] = "Invalid phone number"; $count_errors = count($error); if ($count_errors > 0){ echo "ERROR:<br />"; foreach ($error as $err){ echo "-$err<br />"; } } else { //Other code } ?> So the first part of the IF statement is always executing. $count_errors DOES return 0 when printed out. Any help would be greatly appreciated. Thanks! |
