PHP - Undefined Argument Warnings
Hey all. I have a function called displayForm in a form validation script. This function accepts a few arguments but these arguments are empty upon initial calling of the function. One of the arguments is and errors array that only gets populated if there were form errors.
So upon running my script initially I get missing argument Warnings. Can these warnings simply be ignored? Would they cause problems throughout my script if I ignore these warnings? And how can I suppress these warnings if I would like to? Thanks all for your help. Cheers. Similar Tutorialsok people sorry but its late, and I'm tired and I can't figure this out maybe I just need a break? I'm getting some warnings here, first here is my code: Code: [Select] <?php echo"<?xml version=\1.0\"encoding=\UFT-8\"\x3f>"; echo"\n"; ?> <!DOCTYPE html PUBLIC"-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtmll/DTD/xhtmll-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"lang="en"> <head> <title>Assignment 7: Making Space, Part 3</title> <meta name="author" content="Jim Cozzy"/> </head> <body> <h1> Assignment 7: Making Space, Part 3 </h1> <?php echo "<h2>Today is ".date('l, F d, Y')."</h2>"; ?> <?php //calculate the area of an equilateral triangle function calcTriangle($cVal) { $halfSide = $cVal/2; $otherSide = sqrt(($cVal*$cVal) - ($halfSide*$halfSide)); $areaValue = $otherSide * $halfSide; echo "<p>The area of an equilateral triangle whose sides are {$cVal} is {$areaValue}.</p>\n"; } $yeah = (isset($_POST['vfld']))?$_POST['vfld']:''; if (isset($_POST['submit'])) { if ($_POST['submit'] == "Clear") { $yeah = ""; } elseif ($_POST['submit'] == "Calculate") { if (!eregi(square|circle|triangle, $yeah)) { echo "<p>Sorry I forgot to mention the the shape needs to be a Square, Circle, or a Triangle.</p>".

Notice: Use of undefined constant square - assumed 'square' in /studfs1/homepage/CISS-225/makingspace3.php on line 49 Notice: Use of undefined constant circle - assumed 'circle' in /studfs1/homepage/CISS-225/makingspace3.php on line 49 Notice: Use of undefined constant triangle - assumed 'triangle' in /studfs1/homepage/CISS-225/makingspace3.php on line 49 Is there any way to catch warnings without defining a warning handler? Example: try { $settings = parse_ini_file( 'main.ini' ); } catch( ErrorException $e ) { throw new ErrorException('No main configuration file found for webiste', '0003'); } Only ends up throwing a warning if the file doesn't exist. I want to catch it and throw an error. Okay I have been trying to work out this problem for 3 months I am not the type of person to give up but I have tried everything. I was first not able to connect to my database live with my form but I did a change from ($cxn,$sql) to ($sql,$link) since then I was able to download to phpmyadmin in Google Chrome and no other site. But in Google Chrome I get a message about global registry Warning: Unknown on line 0. all other sites give me a Warning line 116 MySql Link is Here is my coding can someone help I have only been using PHP and I know someone is out there with much more knowledge than I have. This is the first page with the codes but it does not go to the second page which I will paste after this one. Any help would make my year better.

Hope some of the genius here will rub off on me. Very simple example of what is happening: Base.php Code: [Select] class Base_Model //class autoloaded { protected function scrub($value) { return trim(htmlspecialchars($value, ENT_QUOTES, "UTF-8")); } } Foo.php Code: [Select] class Foo_Model extends Base_Model { if($_POST) { $_POST = array_map('parent::scrub', $_POST); } } This works perfectly on the workstation (MAMP) server, but generates a warning ( Warning: array_map() [function.array-map]: The first argument, 'parent::scrub', should be either NULL or a valid callback in... ) when uploaded to the production server. Both are running the exact same version of php. Any ideas would be appreciated on getting rid of the error, besides turning off warnings ( haha ). William I use PHP's PDO extensively for data grabbing and inserting. When I am selecting data, the return is a PHP PDO object which in itself contains select statements. So I use foreach to parse through the object and build a table. For cells which I have data it's fine but for cells which do not get any data meaning that have no entry in the db, php throws out a error PHP Warning: Invalid argument supplied for foreach(). I tried using if(is_array) and also @ to suppress them but no luck . Can anyone point me to the right direction for suppressing these errors/warnings!! In php.ini on my local development server, error_reporting is set to Quote error_reporting = E_ALL | E_STRICT And I get no errors. However, on the remote web server I found a bunch of warnings in the error log. I fixed most of them, but this error/warning should have popped up on my development console: Quote [02-Dec-2011 17:47:22] PHP Warning: array_keys() [<a href='function.array-keys'>function.array-keys</a>]: The first argument should be an array in /home/bpslk/public_html/cart-checkout.php on line 177 [02-Dec-2011 17:47:22] PHP Warning: Invalid argument supplied for foreach() in /home/bpslk/public_html/cart-checkout.php on line 177 I can fix the code to eliminate the warning, no prob. But why am I NOT seeing this error on my development machine? --Thanks --HarryG Hello, I was trying out some code to check out how some of the php settings work and when i tried allow_call_time_pass_reference to see if it works, it doesn't spew out any warning or error like the comments in the .ini file mention (or in the manual sites). Maybe i'm not using some other setting in order to see this? Here is my EXACT code. <?php ini_set('display_errors',1); error_reporting(-1); $variable = 'String'; function display($variable) { return $variable; } echo display(&$variable); ?> Outputs : String. No errors, no warnings. I'm running PHP Version 5.3.2-1ubuntu4.5 Hello, I have just upgraded my wampserver and with it MySQL, PHP and PhpMyAdmin versions. And my scripts, which ran normally before, not burst hundreds of undefined variable and undefined index notices. I realize it's "notices", not "errors" but this is quite irritating. I believe it might be due to some upgrade in PHP scripting rules or something but I don't know what. I hope you can help me. The first type of notice is "undefined variable". This function will return the notice if I remove the bold red line, where I define the variable as empty before I use it in the loop. I didn't need to do this before. function statistics($array) { [color=red][b]$list = '';[/b][/color] if(is_array($array)) { foreach($array as $name => $value) { // Rip out the name of the client. $list .= "<li>".$name." - "; // set an integer so we know how many tier2 values we have read. $x = 0; foreach($value as $difference => $sum_total) { // if this is the more than the first tier2 values, use a '+' between the units. $list .= (++$x > 1) ? " + ".$sum_total." ".$difference : $sum_total." ".$difference; } // close the line out. $list .= "</li>"; } } return $list; } To avoid the 10+ like notices on the page I declare them empty before the variable's first occurrence. But this sounds stupid to me. Wasn't this one of PHP's benefits, not to have to declare the variable before using it? I also get about 30+ undefined index notices, e.g. Quote Notice: Undefined index: COMPANY XXX in F:\wamp\www\Project Management\main.php on line 37 Notice: Undefined index: USD in F:\wamp\www\Project Management\main.php on line 37 Notice: Undefined index: USD in F:\wamp\www\Project Management\main.php on line 41 Here are those lines: $income_total = calculate("income"); foreach($income_total as $row) { $clientID = $row['clientID']; $clientname = $row['clientname']; //$client = "<a href=\"index.php?page=Client&do=view&clientID=$clientID\">".$clientname."</a>"; $client = "<a href=\"index.php?page=Project&do=view&sortby=$clientID\">".$clientname."</a>"; $currency = $row['currency']; $client_sum = $row['client_sum']; $year_sum = ''; $year_sum += $client_sum; $income = ''; $income[$client][$currency] += $client_sum; $income_list = statistics($income); $income_all = ''; $income_all[$currency] += $client_sum; } Line 37 is: Quote $income[$client][$currency] = It's the values assigned to $client and to $currency that seem to cause the notice. How do I deal with this? I don't just want to turn error/notice display off, I want to resolve this issue. my current code: Code: [Select] $Townsearch = $_REQUEST['rsTown']; list($Town, $County) = split('[,]', $Townsearch); ltrim($County,1); I am getting undefined index and undefined offset, so I tried this: Code: [Select] if $_REQUEST['rsTown'] == ''{ $Townsearch = ''; } else { $Townsearch = $_REQUEST['rsTown']; } but this brought back: Parse error: syntax error, unexpected T_VARIABLE, expecting '(' in D:\retroandvintage.co.uk\wwwroot\main.php on line 6 Can someone please help? thanks I am pretty sure I defined these, by making it something like $blah="blah" and `blah` = ' {$blah}' So why am I getting these errors = Notice: Use of undefined constant petid - assumed 'petid' in /home/vhosts/foggyjungle.6te.net/viewpet_forum.php on line 38 Notice: Use of undefined constant adopter - assumed 'adopter' in /home/vhosts/foggyjungle.6te.net/viewpet_forum.php on line 41 Notice: Undefined variable: fulldate in /home/vhosts/foggyjungle.6te.net/viewpet_forum.php on line 44 Fatal error: Call to undefined function showpet_forum() in /home/vhosts/foggyjungle.6te.net/viewpet_forum.php on line 45 $time = mysql_query("SELECT * FROM `pets_adopted`"); $date = mysql_fetch_array($time); $fulldate = "$date[fulldate]"; $halfdate = "$date[halfdate]"; function check(){ $pid = mysql_real_escape_string($_GET['id']); $result = mysql_query("SELECT * FROM `pets_adopted` WHERE `id` = '{$pid}'"); while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $results = mysql_query("SELECT * FROM `pets_list` WHERE `id` = '{$row[petid]}'"); $pet = mysql_fetch_array($results); $results2 = mysql_query("SELECT * FROM `users` WHERE `id` = '{$row[adopter]}'"); $usercc = mysql_fetch_array($results2); There's the snippet.

I want ot know is there a way round this problem? Here is the http://voluntary.awardspace.co.uk/Postcard.php I am absolutely desperate to solve this burning issue Hi all, I don't know php, but i have a script i would like to be able to also run from shell, like: "php script arg1"... if (isset($_SERVER['argc'])) { $postip = $1; } else { $postip = $_POST["ip"]; } How do i assign $postip = $1; (or is it infact $2...) ? My script gives me this error now: PHP Parse error: syntax error, unexpected T_LNUMBER, expecting T_VARIABLE or '$' Thanks in advance :-) ! For some reason I keep getting a recurring error every time someone uses a page on my site.

'<li><a href="?a=show&letter='.$i.'&type='.$type.'">'.$i.'</a></li> ' : '<li class="no_highlight">'.$i.'</li> The code works, but the error message must be showing that I am performing the echo incorrectly.

"\n"; $flag = true; } array_walk($row, 'cleanData'); echo implode("\t", array_values($row)) . "\n"; } ?> Hello, i know this is a very silly question but it bothers me to know the reasoning behind it. My application has a design where the functions are stored in functions.php and variables are stored in variables.php. There are some functions that have variables that i might change often and the reason i don't directly use them in the argument itself is so that in future if i have to change the default argument's value , then i wouldn't have to scroll through all the functions and look for it. I have a slippery memory i know i will be able to remember it better if i store custom global variables separately and custom global functions separately. I tried searching these forums for this but its giving me a message like "search daemon not found" or something like that.. Anyways , coming to the point, i know that PHP doesn't accept variables as default arguments but may i know the reasoning behind this? If i understand the reasoning behind this i know it will stick better in my head.So..why does a function not allow a variable as a default value? Or if anyone has a link to explaining this behaviour in PHP, i would appreciate it if you could pass it on! Thank you I've been challenging myself to get the system() argument working for the past hour and something. I still can't get it working so I ask for assistance. system ("cp /var/www/http/test.com/products/".$fordir['fordir']."/".$category['category']."/".$_POST['id']." /home/n/Documents/My\ Sites/test.com\ codebase"); The error log doesn't say anything, so I suspect that PHP is not even attempting to parse the code. Can anyone spot something that shouldn't be the way it is? How do I make my constructor work when I don't pass in an argument. That is, it should efault to null. Code: [Select] class Something{ private $type=null; public function __construct($t){ $this->type = $t; } public function setSomething($t){ $this->type = $t; } public function getSomething(){ if (is_null($this->type)) { return "None for you!"; } else { return "Something is " . $this->type . "."; } } } TomTees I'm getting this error, but I'm not sure how to fix it (on my Wordpress site).
