PHP - Validation Errors Display Null?
Ok I'm setting the error. I debugged my code and it's catching the phrase in the set_error() function. But it's returning NULL when I try to display it from the display_error() function. These functions are in the form class. I create a new instance of it on the register.php and I'm trying to grab the values. Here is my Form class (only showing the part you need to see):
Code: [Select] class Form { private $error; public function set_error($errmsg){ $this->error = $errmsg; return; } public function display_error() { $error = "<p style='color:red;'>".$this->error."</p>"; return $error; } } Then here is my register process: Code: [Select] if(isset($_POST['submit'])) { if(isset($_POST['name']) && isset($_POST['username']) && isset($_POST['password']) && isset($_POST['password2']) && isset($_POST['email']) && isset($_POST['email2']) && isset($_POST['dob']) && isset($_POST['gender']) && isset($_POST['security'])) { if ($user->register_user($_POST['name'], $_POST['username'], $_POST['password'], $_POST['password2'], $_POST['email'], $_POST['email2'], $_POST['dob'], $_POST['gender'], $_POST['security'])) { $message = "User has been registered successfully."; } else { $message = $form->display_error(); } } else { $message = "Please fill out all parts of the form!"; } } It display the $message just fine when I call isset($message), but it won't display it when I assign it the form->display_error() value because it returns NULL. Thank you! Similar TutorialsI'm trying to display the null values only, where am I going wrong?

Need help Been screwing around on Google for about 3 hours trying to find a tutorial on what I am trying to do with absolutely no luck! I am simply trying to get my test script to echo errors from an array when a form criteria does not validate. This is my final revision which is still not working! Can someone please tell me what I am doing wrong? No matter what I do, I can't get away from this error: Notice: Undefined variable: error in C:\wamp\www\php\form_validation.php on line 13 <?php $o = $error[]; // test echo $o; // test if(!preg_match('/[^0-9A-Za-z]/',$_POST['first_name'])) { $error[] = "Please enter a valid First Name"; ?> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> First Name:<br /> <input name="first_name" type="text" size="50" maxlength="50" /><br /><br /> <input type="submit" /><br /><br /> </form> I have a fairly complicated Q&A Form with 10 Inputs. If there is a data entry error, then I re-load the Form display an error-message beneath the corresponding field. No problems there. Normally, if there was a more serious error (e.g. INSERT failed), then I would re-direct to a new page and display the error (or success) message there. No problem again. But here is where I am confused... Because my code iterates through each of the 10 Inputs on my Q&A Form, there could conceivably be an error on each loop. If I had two serious errors (e.g. INSERT error and UPDATE error), then how should I handle displaying the error?! For those types of errors, I would usually re-direct, however there would usually be only one error to display, e.g. Quote Your profile answers could not be added due to a System Error. Should I display every error that might occur for every one of the 10 Input fields, or does it make sense to just display one error, with the understanding that if one thing fails then everything does. Hope that makes sense?! Thanks, Debbie I have a Q&A Form that consists of 10 Questions with input boxes for 10 Answers. (Each Answer is stored in its own record in the "answer" table.) When the Form is submitted, I loop through an answerArray and decide what to do with each Form Field. For example, if there is a new Answer, then I create a new record by doing an INSERT, but if the Answer is a change, then I do an UPDATE on an existing record. Following my previous coding style, I assign a Results Code for *every* possible thing that can happen in *every* code branch, e.g. Code: [Select] $_SESSION['resultsCode'] = 'ANSWERS_NO_CHANGES_2138'; $_SESSION['resultsCode'] = 'ANSWERS_UPDATE_SUCCEEDED_2139'; $_SESSION['resultsCode'] = 'ANSWERS_UPDATE_FAILED_2140'; $_SESSION['resultsCode'] = 'ANSWERS_INSERT_SUCCEEDED_2141'; $_SESSION['resultsCode'] = 'ANSWERS_INSERT_FAILED_2142'; The problem is that - as my code currently stands - I only end up displaying a resultsCode for the LAST QUESTION, because the first 9 are overwritten?! Should I keep my current structure, and quit on an Errors, and display a page with that error (e.g. Update Failed), and then just comment out the Succeed messages? Or do I get fancy and store each Success or Error in an array and display the outcome for all 10 Questions after the Form is processed? In the past all of this was easy, because ONE FORM equated to ONE RECORD, so Error Messages were easier to display. But here, I have ONE FORM and up to 10 RECORDS?! Hope this is making sense? Thanks, Debbie Hi, i'm a PHP newbie and am working on a contact form which is below. I've just included one field (email) to make things shorter. In practice this works okay but when the page is first displayed it shows the "No Email was entered" error. I know that I need to include something like "if (isset($_POST['submit'])) is true then process the error checking otherwise display the form however I can't seem to find where to put it and spent all weekend on this now, little help? Once i've got this sorted i'll add the other fields and javascript error checking as well.

I want to display a list of the recipe titles in ascending alphabetical order with each title linked to another page that displays all of the information about the recipe. I can't seem to get anything to display though (not even the titles) but I'm not getting any errors returned either. It seems as if there is nothing in the table to display (even though there are 40 records there). Any help would be greatly appreciated. Here is the code I have so far: Code: [Select] <?php $dbhost = 'localhost'; $dbuser = '*****'; $dbpass = '*****'; $dbname = '*******'; $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to database'); mysql_select_db($dbname) or die('Error selecting the database'); // select data from db to use $result = mysql_query("SELECT * FROM recipes ORDER BY title ASC LIMIT 0,50") or die('mysql_error()'.'Error: ' .mysql_errno() ); //display the data while($row = mysql_fetch_array($result)); { echo"<b><center>Healthy Lifestyle Gourmet Recipes</center></b><br /><br />"; echo "<span class=\"recipelink\"><a href=\"reciperesults.php?id=".$row['id']."\" target=\"_blank\">".$row['title']."</a></span><br/>\n"; } mysql_close(); ?> I starred out the connection variables but, they are all correct in my code (I'm not getting the "or die" errors) I am trying to update the database with isset to set the value of the variable to either null or the value entered by the user. Currently, if no value has been entered null is being set as a string causing the date field to populate with zeros. How do I code it so that it populates or sets the value as null and not as string null?

<?php How do I display the actual errors in IIS 7.5? If I miss a semicolon, I get: "HTTP Error 500.0 - Internal Server Error" absolutely useless.

1.)
2.) On my particular coding, I can use either the NULL/isset style, or, the ""/== style, with no errors or ill effects.... but something tells me the expert PHP coders prefer one over the other... Thank you!! Edited July 10 by ChenXiuMy code; $sql = "SELECT SUM(IF(`submitdate` IS NULL , 1 , 0 )) as 'Survey Started But Not Completed' FROM `survey_$surveyid`"; $statement = $dbh->prepare($sql); $statement->execute(); $result = $statement->fetch(PDO::FETCH_OBJ); //pass that data to an objectIs returning;
stdClass Object
(
[Survey Started But Not Completed] =>
)
I need to set this to a vaule that I can actually print out on the screen... Like a "0" for example. At the moment it is just a NULL. How do I do this?? These don't work; $result = 0; $result = array(['Survey Started But Not Completed'] => "0"); I have a php page where user/db info is being passed: <?php include "include/dbc.php"; include "include/header.inc"; $exerciseid = $_POST["exerciseid"]; $duration = $_POST["duration"]; $distance = $_POST["distance"]; $metric = $_POST["metric"]; echo'<h1>Added Activities</h1>'; // name of array echo '<h1>Exercise</h1>'; if (is_array($exerciseid)) { foreach ($exerciseid as $key => $value) { echo $key .' : '. $value .'<br />'; } } // name of array echo '<h1>Duration</h1>'; if (is_array($duration)) { foreach ($duration as $key => $value) { echo $key .' : '. $value .'<br />'; } } // name of array echo '<h1>Distance</h1>'; if (is_array($distance)) { foreach ($distance as $key => $value) { echo $key .' : '. $value .'<br />'; } } // name of array echo '<h1>Metric</h1>'; if (is_array($metric)) { foreach ($metric as $key => $value) { echo $key .' : '. $value .'<br />'; } } ?> And here is the output from that code: Added Activities Exercise 0 : Canoeing, on camping trip 1 : Canoeing, rowing, over 6 mph, vigorous effort 2 : Canoeing, rowing, crewing, competition 3 : Canoeing, rowing, light effort 4 : Canoeing, rowing, moderate effort 5 : Diving, springboard or platform 6 : Kayaking 7 : Sailing, boat/board, windsurfing, general 8 : Sailing, in competition 9 : Skiing, water 10 : Ski-mobiling, water 11 : Skin diving, scuba diving, general 12 : Snorkeling 13 : Surfing, body or board 14 : Swimming laps, freestyle, fast, vigorous effort 15 : Swimming laps, freestyle, light/moderate effort 16 : Swimming, backstroke, general 17 : Swimming, breaststroke, general 18 : Swimming, butterfly, general 19 : Swimming, leisurely, general 20 : Swimming, sidestroke, general 21 : Swimming, sychronized 22 : Swimming, treading water, fast/vigorous 23 : Swimming, treading water, moderate effort 24 : Water polo 25 : Water volleyball 26 : Whitewater rafting, kayaking, or canoeing Duration Canoeing, on camping trip : 20 Canoeing, rowing, over 6 mph, vigorous effort : Canoeing, rowing, crewing, competition : Canoeing, rowing, light effort : Canoeing, rowing, moderate effort : Diving, springboard or platform : Kayaking : Sailing, boat/board, windsurfing, general : Sailing, in competition : Skiing, water : Ski-mobiling, water : Skin diving, scuba diving, general : Snorkeling : Surfing, body or board : Swimming laps, freestyle, fast, vigorous effort : Swimming laps, freestyle, light/moderate effort : Swimming, backstroke, general : Swimming, breaststroke, general : Swimming, butterfly, general : Swimming, leisurely, general : Swimming, sidestroke, general : Swimming, sychronized : Swimming, treading water, fast/vigorous : Swimming, treading water, moderate effort : Water polo : Water volleyball : Whitewater rafting, kayaking, or canoeing : Distance Canoeing, on camping trip : 20 Canoeing, rowing, over 6 mph, vigorous effort : Canoeing, rowing, crewing, competition : Canoeing, rowing, light effort : Canoeing, rowing, moderate effort : Diving, springboard or platform : Kayaking : Sailing, boat/board, windsurfing, general : Sailing, in competition : Skiing, water : Ski-mobiling, water : Skin diving, scuba diving, general : Snorkeling : Surfing, body or board : Swimming laps, freestyle, fast, vigorous effort : Swimming laps, freestyle, light/moderate effort : Swimming, backstroke, general : Swimming, breaststroke, general : Swimming, butterfly, general : Swimming, leisurely, general : Swimming, sidestroke, general : Swimming, sychronized : Swimming, treading water, fast/vigorous : Swimming, treading water, moderate effort : Water polo : Water volleyball : Whitewater rafting, kayaking, or canoeing : Metric 0 : mile 1 : mile 2 : mile 3 : mile 4 : mile 5 : mile 6 : mile 7 : mile 8 : mile 9 : mile 10 : mile 11 : mile 12 : mile 13 : mile 14 : mile 15 : mile 16 : mile 17 : mile 18 : mile 19 : mile 20 : mile 21 : mile 22 : mile 23 : mile 24 : mile 25 : mile 26 : mile As you can see, null values are being passed as well.
