PHP - Can't Understand Why My Function Won't Work...
Hi everyone,
It's been awhile since I've coded in PHP and I can't figure out whats wrong with my code... I have a simple function to grab a field from my database and return it. I can make it work without the function, but when I implement it as a function, it breaks - no error, just a blank page. This works fine: $page = "page_about"; $sql = "SELECT body FROM " . $page . " WHERE id=1"; $result = @mysql_query($sql,$connection) or die(mysql_error()); $row = mysql_fetch_array($result); $display = $row[0]; But this does not: function grabBody($page) { $sql = "SELECT body FROM " . $page . " WHERE id=1"; $result = @mysql_query($sql,$connection) or die(mysql_error()); $row = mysql_fetch_array($result); return $row[0]; } $display = grabBody("page_about"); If anyone has any idea whats wrong, please let me know!! Thank you, - Jeff Miller Similar Tutorials
I want to use array_pop to remove the last item added to the SESSION array. So it would remove the REQUEST item. The problem is that nothing is left in the session array because I pop off the last item each time that the form is submitted. Maybe I need to use array_push to push the popped items back on to the SESSION array after the logic has been applied. I don't understand how array_pop is supposed to work on a SESSION array. Can anyone explain to me what behaviour to expect? I expected to get a SESSION array with the REQUEST item removed but I thought that I would still have all of my SESSION items. function garland_separate_terms($node_taxonomy) { if ($node_taxonomy) { //separating terms by vocabularies foreach ($node_taxonomy AS $term) { $links[$term->vid]['taxonomy_term_'. $term->tid] = array( 'title' => $term->name, 'href' => taxonomy_term_path($term), 'attributes' => array( 'rel' => 'tag', 'title' => strip_tags($term->description) ), ); } //theming terms out foreach ($links AS $key => $vid) { $terms[$key] = theme_links($vid); } } return $terms; } this is a function from someone, i couldn't know it very well,sincerely expect someone can explain it to me .thank you. first, the function put an array $node_taxonomy as the parameter. why he didn't declare this ($node_taxonomy = array() then in the foreach loop's statement, why there is no echo to output somethig.but the fact is giving a two-dimension array to $links[$term->vid]['taxonomy_term_'. $term->tid]. Hello all. I'm learning Object oriented php and found this simple piece of code online but i don't understand why the variable $con must be returned: Code: [Select] class Connect { public static function con() { $con=mysql_connect("localhost","root","");// Connects to DB??? mysql_query("SET NAMES 'utf8'"); // Sets charset to UTF8 mysql_select_db("blog"); // Selects the DB return $con; // Don't know why $con must be returned, but it wont work without this. } } $con is later used in the script like this from another class to run a Query: Code: [Select] mysql_query($somequery,Connect::con()); Thanks for your help. When I put this chunk of code into it's own function: function fetch_all ($dbc, $query) { include ('knuffix_list_func.php'); pagination_start ($dbc, $query); $offset = $pag_array[0]; $rows_per_page = $pag_array[1]; $query = $query . " LIMIT $offset, $rows_per_page"; echo "test query: " . $query; knuffix_list ($query, $dbc); pagination_end ($pag_array); } And when I echo out the query as you can see in the example, then I notice that the variables $offset and $rows_per_page never get appended. I set the variable $pag_array to a global inside the function pagination_start(). It usually works when I DON'T wrap a function around this chunk of code, but if I do wrap a function around everything then the global suddenly won't work anymore. Btw, this also won't work if I wrap a function around the function DECLARATIONS. Any ideas, how I could make it work? All the tables are correct and it's making the connect to the database fine it's just not working, did I write it wrong? Code: [Select] function newPm($to, $from, $title, $text){ $q = $db->query("SELECT * FROM ibf_message_topics ORDER BY mt_id DESC"); $lastMsg = $db->fetch_assoc($q); $mid = $lastMsg['mt_id'] + 1; $msgId = $lastMsg['mt_msg_id'] + 1; $db->query("INSERT INTO ibf_message_topics SET mt_id=$mid, mt_msg_id=$msgId, mt_date=". time(). ", mt_title='$title', mt_from_id=$from, mt_to_id=". $to. ", mt_vid_folder='in', mt_read=0, mt_owner_id=$to, mt_user_read=0") or die(mysql_error()); $db->query("INSERT INTO ibf_message_text SET msg_id=$msgId, msg_date=". time() .", msg_post='$text', msg_sent_to_count=1, msg_author_id=$from") or die(mysql_error()); $userq = $db->query("SELECT new_msg FROM ibf_members WHERE id = $to"); $userData = $db->fetch_assoc($userq); $msgCount = $userData['new_msg'] + 1; $db->query("UPDATE ibf_members SET new_msg=$msgCount, show_popup=1 WHERE id = $to") or die(mysql_error()); } Here's how that function is being called in the beginning of the page: Code: [Select] if($action =="banUser"){ $expire = time() + (3600000 * 24 * $_GET['duration']); $q = $db->query("SELECT * FROM ibf_message_topics ORDER BY mt_id DESC"); $lastMsg = $db->fetch_assoc($q); $mid = $lastMsg['mt_id'] + 1; $msgId = $lastMsg['mt_msg_id'] + 1; $title = "Notification"; $duration = $_GET['duration'] ." days"; if($_GET['duration'] == "1"){ $duration = "1 day"; } if($_GET['duration'] == "Forever"){ $duration = "forever"; } $temp = 0; if($expire > time()){ $temp = 1; } $body = "This automated message has been sent to notify you that your account has been banned $duration.

I am having trouble getting the delete function to work. I pick the user that I want to remove from the system. I verify that this is the right person to remove. Then the record is deleted from the database. The part that picks the person and verifies that it is the right person to remove from the database work fine. It is the part that actually deletes the record. It takes me back to the pick_user.php.

I am having an issue with a support ticket program. I have added a feature to this program that allows my staff members to add multiple users to a ticket. The problem I am having because I am new to PHP is how do I email the users when they have been added to the ticket. Below is the code I am using for add user. If someone could look at it and help me figure out how to get this to email the user when they are added to the support ticket that would be great.

I am currently hosting my website on my own dedicated server, and i am trying to use the mail() function, but for some reason it doesn't send the email.
This is my php code:
the *** are real addresses.
The from is admin@host.com
<?php $to = "****"; $subject = "Test mail"; $message = "email message."; $from = "***"; $headers = "From:" . $from; mail($to,$subject,$message,$headers); echo "Mail Sent."; ?> Edited by Tzahi_ben_artzi, 02 October 2014 - 02:44 PM. I am using PHP 5.5 on windows 8 and I am trying to localize my website to multiple languages while everything is OK on remote host , the gettext function does not work correctly in my localhost. I have implemented the whole tutorial of http://www.sitepoint...applications-1/ step by step but it seems setlocale(LC_ALL, "en_US") fails and I don't know how to correct or install "en_US" in my system. when I use "en-US" instead of "en_US" the sellocale function does not return FALSE but again the gettext function return the original string.
Hi, Im learning php, but Im a bit confused on this basic problem. I have the following code: <?php include "tax.php"; $price = 95; echo "Price before tax: $price <br>"; echo "Price after tax: "; echo add_tax ($price); ?> Which uses the function below <?php function add_tax ($amount) { $total = $amount * 1.09; return $total; } ?> When I execute the code I can see that it does work, but I do not understand why this part works! echo add_tax ($price); There is no multiplier symbol here, so is the function performed on the ($price) variable simply because of where it is located on this line of code? Thanks I am attempting to build an online shopping cart, however I have a problem with the Delete /Remove Item function. Add New and Update Item work perfectly fine, just the Remove Item doesn't. It seems to be mirroring the same functionality as Update Item. http://www.tottonc.co.nz to see my problem in action. Any help or solutions would be much appreciated... Well PHP manual says that the script execution will be delayed by $x seconds if you write a codes like this: Code: [Select] $x = 5; //5 secs sleep($x); Now I have this script in which I write the four lines to the screen one by one, each should be delayed by 5 secs after the last line is output to the screen. It does not work out at all... Code: [Select] echo "Update setting 1:"; sleep(5); echo "Success! <br>Updating setting 2"; sleep(5); echo "Success! <br>Updating setting 3"; sleep(5); echo "Success! <br>Updating setting 4"; Instead, the entire script execution is delayed by 15 secs, with all four lines output at the same time. Why is this happening? Is there a way to fix it? Please help... hi guys. i'm new to php and Apache and i have a problem. i'm trying to execute an exe file that i have in my folder, and the code i use is Code: [Select] echo exec('test.exe');i have tried using this with and without the ".exe." and still no luck. i have also tried using a different path Code: [Select] echo exec('C:\Windows\System32\mspaint');now these codes work when i run them from my php editor(PhpED), bun when i try running it on Apache it gets stuck. (just shows the web page as loading with no end. please help me out. i'm guessing it something with security. also if there is any other code i can use please let me know (i have also tried using system) I haven't had a problem with sql injection yet, but I'm scarred to death. I didn't do any form data validation as I was building my site. I'm just now starting to learn how. Magic_quotes is turned on at my host. I know about htmlspecialchars and mysql_real_escape_string and stripslashes and htmlentities. In testing each of these, it seems they all miss one thing or another. so, I created an array of words and characters that I can't for the life of me imagine anyone would ever need on any form in my site, that I THINK addresses most if not all of the really bad things. But hey... I'm new to this. So here is my array and using print_r() it looks pretty good. Code: [Select] $badstuff = array('select','delete','update','insert','drop','=',';','"','\'','<','>','/'); Code: [Select] Array ( [0] => select [1] => delete [2] => update [3] => insert [4] => drop [5] => select [6] => delete [7] => update [8] => insert [9] => drop [10] => = [11] => ; [12] => " [13] => ' [14] => < [15] => > [16] => / ) My str_ireplace() function works fine within the code, but I'd like to create a function using str_ireplace(). I am failing miserably. Here is my function that doesn't work... Code: [Select] function strip($string){ return str_ireplace($badstuff,"",$string); } Here below..... the first line, that uses the function does NOT work. The second line that just uses str_replace() function works fine. Code: [Select] echo strip($string).'<br>'; echo str_ireplace($badstuff,"",$string) Can anyone tell me why my function does not work? I've read and watched 20 tutorials and just can't see the problem. Thanks for any input. but never on the first call. Okay, I posted this on StackOverflow but no one there seems to have an answer either. I have this simple function: Code: [Select] public function delete($messageID) { $type = $this->findType($messageID); if ($type == 'in') { foreach ($this->inArr as $key => $value) { if ($this->inArr[$key]->messageID != $messageID) $implodeData[$key] = $this->inArr[$key]->messageID; } if (!isset($implodeData)) $imploded = '0'; else $imploded = implode(',', $implodeData); $result = $this->_database->updatePMUser('inArr', $imploded, 'UID', $this->UID); $result2 = $this->_database->deletePM('messageID', $messageID); return; } else { foreach ($this->sentArr as $key => $value) { if ($this->sentArr[$key]->messageID != $messageID) $implodeData[$key] = $this->sentArr[$key]->messageID; } if (!isset($implodeData)) $imploded = '0'; else $imploded = implode(',', $implodeData); $result = $this->_database->updatePMUser('sentArr', $imploded, 'UID', $this->UID); $result2 = $this->_database->deletePM('messageID', $messageID); return; } } It is a delete function for a private messaging program for a forum script I'm writing. Anyway, here's the issue - it works! But only sometimes. It is called in 3 different places, always from a form processing class I have, once in the view message section to delete a message you're viewing, in a foreach from the sentbox options section and then a foreach in the inbox options section. The inbox and sentbox option sections do that whole "delete the checked messages" for the mass removal functionality. The delete function above works in all ways shapes and forms when I use it in single calls - like when I'm deleting a message while viewing it or when I only check one message from the inbox, etc - but when I call it multiple times (as in I have checked multiple messages) - it fully deletes one (both the message and the reference to the message in the user's db row) and then only deletes the actual message on the others (deleting the message is the call to deletePM - deleting the reference is the call to updatePMUser). Okay, if you need further information - the function above checks the type the message is (in the inbox or in the sentbox) and then uses that to foreach through that array (inArr or sentArr) of the user. It logs in all the messageIDs of the those that DON'T match the one we're deleting and then at the end it implodes those caught IDs into a string that is then updated in the user's row as a comma separated string of values each representing a message in the DB - you get the picture. I realize I have some trimming to do (for one I can cut the above function down by about half by using variable variables) but I'll get to that after I get the thing working. I can't figure out why it's doing what it's doing. If you need the function that calls this in the foreach, I have it below. Oh, and the thing that really boggles me is that this function is called fully for each checked message in the foreach - it fully returns and then loops - if it works once, I don't see how it wouldn't work on a second call from a loop - the variables it uses should be trashed when it leaves the function, they aren't global or object properties or anything. Color me confused. Thanks for any help, oh, here's one of the functions that calls it to delete checked messages (this one is for the sentbox, there is another for the inbox): Code: [Select] private function _processSelectedSent() { $pmObj = unserialize(base64_decode($_POST['pmObj'])); $i=1; foreach ($_POST as $key => $value) { if ($value == 'marked') { $checkedArray[$i] = $key; $i++; } } if ($_POST['submitter'] == 'Delete Selected') { if (is_array($checkedArray)) { foreach ($checkedArray as $key => $value) $pmObj->delete($value); } else $pmObj->delete($checkedArray[1]); header("Location: ".HOME_PAGE.PM_PAGE."?view=sentbox&nocache=".time()); } } ok guys, another issue for me i cannot find an answer for. according to this thread: https://stackoverflow.com/questions/8803994/php-mail-not-working-for-some-reason, mail() doesn't work when smtp is not configured properly. I checked my server files and I do not have a .ini file. am I spose to have one by default? and, according to this question in the godaddy community: https://www.godaddy.com/community/Using-WordPress/PHP-ini-how-to-make-changes-using-cPanel/td-p/119704, configuration of PHP in general should be done in the .user.ini file instead of in php.ini. the following code, which is what I have now, results in no mail being sent to my address so either my code is wrong or my configs are not set properly I'm guessing:
if( empty($errors))
{
$to = '$myemail';
$email_subject = "Demo Request Submitted";
$email_body = "A demo request was submitted through your website with the following information:" .
"Contact Name: " . $contact . " </br>" .
"Company: " . $company . " </br>" .
"Email: ". $email . " </br>" .
"Phone: " . $phone . " </br>" .
"Best Time to Contact: " . $best_time_to_contact . " </br>" .
"Message: " . $message;
$headers = "From: " . $myemail . "\n";
$headers = "From: $email\r\nReply-To: $email\r\nReturn-Path: $email\r\n";
mail($to, $email_subject, $email_body, $headers);
echo "Your demo request has been sent.";
} else {
echo $errors;
}
also, in the stackoverflow article I mentioned above, one of the responders suggests using PHPMailer as a better way to send mail using PHP. Is that true? I've always used mail() in the past and I've never been let down in terms of a message *not* being sent. PHP.net says the same thing as the response from stackoverflow as well. thanks!

It works perfectly in regular browser mode, but gives me this error on Cli mode if I do convertToCamelCaps('TEST STRING'); PHP Catchable fatal error: Argument 1 passed to convertToCamelCaps() must be an instance of string, string given in file... if (!function_exists('convertToCamelCaps')) { function convertToCamelCaps(string $string, $initialCaps=FALSE) { if ($words = explode(' ',$string)) { foreach ($words as $index => &$word) { $word = strtolower($word); if($index==0 && $initialCaps===FALSE) { continue; } $word = ucwords($word); } return implode('',$words); } return FALSE; } } If I remove the string datatype requirement in the function before the function argument list, it works fine in CLi mode. |
