PHP - Blank Pages And Error Display
I am writing a database using php mysql. I have a page which works fine but if I add one extra query it just produces a blank page. I remember once that someone said I could put in some code at the start of the page and it would display any errors but can't remember the code!
Could someone let me have the code and does anyone have any suggestions as to why this blanking is happening?
Many thanks
Similar TutorialsHi everyone, I am a beginner web designer and a novice php user. I am a regular forum user and understand that you should always do a search and try to find the answer yourself but I have done that and didn't get any results (or I didn't understand them!). So I ask for some assistance - either you can tell me the code or link me to the correct answer. I am working on a website that I have built a enquiry form for and it has a php script for it. I have managed to get the form running properly and got the reCaptcha working correctly (with a custom error page) but I do not understand how to add custom error pages for incomplete email addresses, empty email addresses, or for a blank form? I tried using the same tactic I used for the reCaptcha error page but it didn't work - probably because I was guessing and just tried it in a bunch of different places. The error msg that displays now is just a plain white page with the msg - Email address is invalid appearing at the top left. While this is suitably functional it doesn't really look like much so I want to build a custom page for each error that could happen. So the code is below - if anyone can point a beginner in the right direction I would be super happy. :mrgreen: if you need anymore code or other details just tell me and I will post them up. The url of the form page is http://www.sunsolutionshomeimprovement.com/onlinesales.html This is the code I think you will need - I got it from a demo php script that I have modified. As I said I don't have much clue what I'm doing so I just posted it exactly how it looks - if I over did it I apologize... :oops: 68.// Validate email field. 69. 70.if(isset($_REQUEST['email']) && !empty($_REQUEST['email'])) 71.{ 72. 73.if(preg_match("/(%0A|%0D|\n+|\r+|:)/i",$_REQUEST['email'])){$errors[] = "Email address may not contain a new line or 74.a colon";} 75. 76.$_REQUEST['email'] = trim($_REQUEST['email']); 77. 78.if(substr_count($_REQUEST['email'],"@") != 1 || stristr($_REQUEST['email']," ")){$errors[] = "Email address is invalid";}else{$exploded_email = explode("@",$_REQUEST['email']);if(empty($exploded_email[0]) || strlen($exploded_email[0]) > 64 || empty($exploded_email[1])){$errors[] = "Email address is invalid";}else{if(substr_count($exploded_email[1],".") == 0){$errors[] = "Email address is invalid";}else{$exploded_domain = explode(".",$exploded_email[1]);if(in_array("",$exploded_domain)){$errors[] = "Email address is invalid";}else{foreach($exploded_domain as $value){if(strlen($value) > 63 || !preg_match('/^[a-z0-9-]+$/i',$value)){$errors[] = "Email address is invalid"; break;}}}}}} 78. 79.) 80. 81.// Check referrer is from same site. 82. 83.if(!(isset($_SERVER['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']) && stristr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']))){$errors[] = "You must enable referrer logging to use the form";} 84. 85.// Check for a blank form. 86. 87.function recursive_array_check_blank($element_value) 88.( 89. 90.global $set; 91. 92.if(!is_array($element_value)){if(!empty($element_value)){$set = 1;}} 93.else 94. 95. 96.foreach($element_value as $value){if($set){break;} recursive_array_check_blank($value);} 97. 98.) 99. 100.) 101. 102.recursive_array_check_blank($_REQUEST); 103. 104.if(!$set){$errors[] = "You cannot send a blank form";} 105. 106.unset($set); 107. 108.// Display any errors and exit if errors exist. 109. 110.if(count($errors)){foreach($errors as $value){print "$value<br>";} exit;} 111. 112.if(!defined("PHP_EOL")){define("PHP_EOL", strtoupper(substr(PHP_OS,0,3) == "WIN") ? "\r\n" : "\n");} 113. 114.// Build message. I don't think there is anymore that is relevant? I just want to reiterate that I know nearly nothing about this stuff so if you could keep your answers simple it would help a lot - cheers! I don't think php is installed/enabled?! Hi, I've inherited a website with a problem! Basically the site runs pommo mailing list, which has worked fine for years. Recently though the website domain name changed. Since then - or at least at a similar time - pommo has just stopped working completely. It does nothing but outputs blank pages. I've never done any php development so I've no idea where to start in terms of debugging this. I've checked that the files etc all exist on the server: they do. I've uploaded a test html page which works. I've uploaded a test php page containing: <?php phpinfo( ); ?> and it works. But when I visit any page in the pommo application, the browser just renders a totally empty white page - no source HTML at all, just nothing! Can anyone suggest how to debug this? Even an error message would be somewhere to start. Thanks all! Ok when I run this code is displays nothing but a white page.. No error or anything. I have commented the first two segments of code the rest should be self explainable. Ok my beauty of a script: Any help to improve and or modify would be great as well as helping with the problem at hand.

I am using an API from jambase.com to display events on a php page. Everything works great, the xml file is read and the data is displayed on the page as it should. My only problem is that when the data is displayed there is always a blank area where the first record of data should go. Any ideas how to get rid of this? http://www.wddclients.com/mag33/events_search.php (artist search field not enabled yet) Hopefully this is something pretty minor but if anyone wants to see specific code I can supply that.

Brian Hello everyone, Very new to coding - enjoying it but struggling! I think I'm trying to do something pretty common but I seem to have come up against a complete wall now and after hours/days searching the internet and reading books I'm completely stuck! I'm trying to write some code to search a MySQL database of products, then display the results. For some search results there will be lots of products so I want to display 10 products on the first page then allow visitors to go to the next page to see another 10, and so on - a type of pagination, as they should then be able to click back to see the last page etc. I've got to the point of being able to display the first 10 search results, but I can't figure out at all how to create some kind of page scrolling/pagination system. Please, does anybody have any ideas?? I've attached my code, I hope this is the correct way of doing things here. Many thanks for your time! The PHP search code... Code: [Select] <?php //opens connection to mysql server $dbc = mysql_connect('localhost'); if (!$dbc) { die('Not connected :' . mysql_error()); } echo "Connected to mysql database<br />"; //select database $db_selected = mysql_select_db("NAME_OF_DATABASE", $dbc); if (!$db_selected) { die ("Cannot connect :" . mysql_error()); } echo "Connected to database<br /><hr />"; echo "Here are your results"; $term = $_POST['term']; $category = $_POST['category']; $brand = $_POST['brand_name']; $sql = mysql_query("SELECT * FROM products where product_name like '%$term%' AND category_name like '%$category%' AND brand_name like '%$brand%' LIMIT 0, 10"); { while ($row = mysql_fetch_array($sql)){ echo "<table border='1' width='100%'> "; echo "<tr>"; echo "<td style='vertical-align:top' width='25%'>" . '<img src="', $row['image_url'], '" alt="', $row['product_name'], '" width="100" height="100" />' . "</td>"; echo "<td style='vertical-align:top' width='50%'>" . $row['product_name']; echo "<br />"; echo "<span style='font-size: 10px'>" . $row['description'] . "</span>" . "</td>"; echo "<td style='vertical-align:top' width='25%'>" . $row['price']; echo "<br />"; echo "<br />"; echo "<hr />"; echo "$row['merchant_name'] </td>"; echo "</tr>"; } echo "</table>"; } ?> In the code below, I am trying to produce a google-like page where the user can type keywords and pages of search results are displayed. The main difficulty I am encountering is that when the browser changes pages, it forgets everything about current data. Perhaps I should include the display of pages inside the HTML form ? How can I fix this code ? Here is the contents of my searchpage.php file :
<?php
$keywords='';
$display_search_results='';
if(isset($_POST['search_submitted'])) {
$keywords=$_POST['keywords'];
$search_results=array();
$totalNbrOfItems=20;
for($k=1;$k<=$totalNbrOfItems;$k++) {
$search_results[$k]='Your keywords '$keyowrds.' have been found in item number '.$k;
}
$nbrOfItemsParPage = 5;
$nbrOfPages = ceil($totalNbrOfItems / $nbrOfItemsParPage);
// Compute current page
$current_page = (isset($_GET['page']))?intval($_GET['page']):1;
$display_pages=($nbrOfPages<2)?'<p>Page : ':'<p>Pages : ';
for ($i = 1 ; $i <= $nbrOfPages ; $i++)
{
if ($i == $current_page) //No link to the current page
{
$display_pages=$display_pages.$i.' ';
}
else
{
$display_pages=$display_pages.'<a href="searchpage.php?'.
'page='.$i.'">'.
$i . '</a> ';
}
}
$display_pages=$display_pages.'</p>';
$display_items='';
$start=$nbrOfItemsPerPage*($current_page-1);
for($k=1;$k<=$nbrOfItemsParPage;$k++) {
$display_items=$display_items.($search_results[$start+$k]).'<br>';
}
$display_search_results=$display_pages.$display_items;

Hi im a little stuck... What im trying to do is when you request a page that is not there it goes to a custom error page. I have set the redirect via the .htaccess file. Basicly what im trying to do is only have one php file which displays the server response i.e. 404 error or 401 error and so on rather than having several error pages. So in the code Code: [Select] <h1>Oopppsss!!!! <!-- ERROR TO DISPLAY HERE i.e. 404 page not found --></h1> <p>There seems to be a problem... The page you are looking for does not exist or has moved. This is a permanent error. If you think this is a mistake please get in touch either by giving us a ring on 101010 or by filling out the web form on the <a href="contact-me.php">contact me</a> page...</p> Any thaught on how i can do this or is it not possible... Cheers Sorry for my bad english but i hope you would understand my query. How can i set 404 not found for database driven pages..? I am using header("HTTP/1.0 404 Not Found"); in my 404 error page and ErrorDocument 404 /404.html, whereas 404.html is my error page. i have an URL http://www.example.com/folder/my-test-for-url-95/ which is opening correctly because it has existence on database. but when i am opening http://www.example.com/folder/my-test-for-url-951/ which has existence on database is also opening without any information but i want here a 404 not found page. How can i do so. Thanks Can someoneplease help, I need to setup an error page like IF Username and Password are wrong then show an error also if there is no username or password in the fields and I just click LOGIN, I get a blank page?! Can someone please help me here or point me to a relevant tutorial? thanks here is my page: http://www.retroandvintage.co.uk/default.php here is my code: Code: [Select] <?php session_start(); include_once("config.php"); $ebits = ini_get('error_reporting'); error_reporting($ebits ^ E_NOTICE); /* Login script: This script does the following: Checks that the user is NOT already logged in - if they are they are redirected to the members page by the 'checkLoggedIn()' function. Checks if the login form has been submitted - if so, the 'login' and 'password' fields are checked to ensure they are of the correct format and length. If there are any problems here an error is added to the $messages array and then the script executes the 'doIndex()' function - this function basically outputs the main 'index' page for this script - ie the login form. If there are no problems with the previous step, the 'login' and 'password' field data is passed to the 'checkPass' function to check that an entry exists in the 'users' table for that login/password pair. If nothing is returned from the 'checkPass()' function, an error is added to the $messages array and the 'doIndex()' function is called as above. If a row of data is returned from the 'users' table, the data is passed to the 'cleanMemberSession()' function - which initializes session variables and logs the user in. The user is then forwarded to the members page.

Right know it's close to being done, but I have one problem.. My problem is that if a user has >= 1 message in their inbox it shows what it should, but if the user has nothing in the inbox it shows nothing instead of the simple error "You have no message in your inbox". Code 1: $inbox_a = mysql_query("SELECT * FROM notifications WHERE recieverid='". $_SESSION['id'] ."'") or die(mysql_error()); Code 2: <?php if(!mysql_num_rows($inbox_a) <= 0) { ?> <tr class="table"> <td class="name"><a href="usercp.php?usercp=inbox&id=<?php echo $msgid; ?>"><h3><?php echo ucFirst($msgname); ?></h3></td> <td class="revision"><h3><a href="#"><?php echo $msgsendername ?></a></h3></td> <td class="votes"><h3><?php echo date('D, M d, Y h:i A', strtotime($msgdate)) ?></h3></td> </tr> <?php } else { ?> <tr class="table"> <td class="name">You have no messages in your inbox.</td> <td class="revision"></td> <td class="votes"></td> </tr> <?php } ?> Here I use two php page with two forms. my first form is 'sign_up.php' and second is select_subject.php'. sign_up.php page has more categories and users can select up to 3 more categories there. So. after selecting and user click the continue bottom, page want to go to second form page its select_subject.php page. If a user not select a category of who selected over 3 category I need to display a error message. like this "Please select atleast 1, not more than 3 categories." I use this HTML my first page Code: [Select] <form method="post" action="select_subject.php"> <my select boxes> </form> Then I process it in my second page and if user have made a mistake in first page I need to redirect to the first page again with relevant error message. So I use this code in my second page. Code: [Select] } else { // No valid ID, kill the script. $_SESSION['errors'] = "Please select atleast 1, not more than 3 categories."; $url = 'http://localhost/lanka_institute/tutorsignup/tutor_registration.php'; // Define the URL: ob_end_clean(); // Delete the buffer. header("Location: $url"); exit(); // Quit the script. } and my first page I use this Code: [Select] if (isset($_SESSION['errors'])) { echo '<p> ' . $_SESSION['errors'] . '</p>'; } unset($_SESSION['errors']); but it is not printing my error message in the first page that Im expecting. But it printing 'Array' instead of my message. can you help me, what is the mistake that I have done??? thanks in advance. How is it possible, in PHP, to display an error message next to a form input text field if a user is attempting to submit a form with empty fields? Moreover, how is it possible to remove the same error message when the user fills in the input field with the required data and/or refreshes the page? I have 2 files that I am working with: application.php and process.php.
application.php mainly has the HTML of the form. I am very new to learning PHP (I started learning it last week) and I have been searching for hours for a clear answer. I have already tried different methods for generating the error message including: using empty(), !isset, $_POST["name"] = "", etc, and have tried using session_start();, $row, echo, print, and other variables to try and display error message on the page, and I have tried using unset();, and = null, to try and remove the error message once the input field has been filled but all to no avail. Either the method I try only half works, or nothing works, and I cannot pinpoint which is the part that is not working. I only have 2 files to work with, and as an example of what I want to do is:
1. If the first name field is empty when the user clicks submit, an error message should appear next to the input. Is this possible with PHP? is it possible to disable warnings on a specific page? php.ini set to show warnings Hello: I am trying to select all the records from a table, and display them. Having an issue... This is the code: Code: [Select] <ul> <?php $query = mysql_query("SELECT id,mySectionTitle FROM myWebSiteData"); while($menuData = mysql_fetch_array($query)) { <li><a href="a_websiteData.php?id=" .echo $menuData['id'] ."">echo $menuData['mySectionTitle']</a></li> } ?> </ul> This is the error: Code: [Select] Parse error: syntax error, unexpected '<' in /html/admin/a_websiteData.php on line 91 line 91 is the one that starts with "<li>" What am I missing, or what would be the best way to do this? I'm getting an error: Undefined offset: 1 in… I'm trying to display a 2D array after filling it. It displays fine if I echo it while it's being made, but after it is not working.
I'm making a pyramid solitaire game and am trying to set up the pyramid of cards. There are 7 arrays, each with a set amount of cards in them. The first array only gets one cards while the last array gets seven. This makes it like a pyramid. All the indexes that don't get a card are set to 0. So it looks like this where the 1's are cards:
1 0 0 0 0 0 0 0
1 1 0 0 0 0 0 0
1 1 1 0 0 0 0 0
1 1 1 1 0 0 0 0
1 1 1 1 1 0 0 0
1 1 1 1 1 1 0 0
1 1 1 1 1 1 1 0
1 1 1 1 1 1 1 1
The display2Darray function is what is causing the error. Specifically this line:
if($array[$i][$j] == 0)Heres my main code:
<?php
include_once "pyramidCard.php";
include_once "pyramidDeck.php";
$theDeck = new Deck();
$pyramid = array(array(), array(), array(), array(), array(), array(), array());
$size = 7;
$theDeck->shuffleCards();
makePyramid($pyramid, $size, $theDeck);
display2Darray($pyramid, $size);
//************************
// FRUNCTIONS *
//************************
function makePyramid($array, $size, $deck)
{
$row = 0;
for($i = 0; $i < $size; $i++)
{
for($j = 0; $j < $size; $j++)
{
if($j > $row)
{
$array[$i][$j] = 0;
//echo ". <br>";
}
else
{
$array[$i][$j] = $deck->dealCards();
//echo "this card is ".$array[$i][$j]->getFace()." of ".$array[$i][$j]->getSuit()."<br>";
}
}
$row++;
}
}
function display2Darray($array, $size)
{
for($i = 0; $i < $size; $i++)
{
for($j = 0; $j < $size; $j++)
{
if($array[$i][$j] == 0)
echo " ";
else
echo $array[$i][$j]->getFace()." of ".$array[$i][$j]->getSuit();
}
echo "<br>";
}
}
?>
