PHP - Function By Reference Not Executing
OK, so I have the following file that has database functions:
<?php function dbDelete($param){ $conDelete = mysql_connect($url,'username','password',true); mysql_select_db('my_db',$conDelete); mysql_query($param,$conDelete); mysql_close(); if(isset($conDelete)){ mysql_close($conDelete); } } ?> I include the above file in a session handling file. But for some reason the new file can't call the above function as follows: <?php include_once 'the above stated file'; function timeOut(){ dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'"); $_SESSION = array(); setcookie(session_name(),'',time()-4200); session_destroy(); } //CHECK FOR TIMEOUT REQUEST switch($_GET['xyz']){ case 'timeout': timeOut(); header("Location: /?xyz=timedout"); break; case 'logout': timeOut(); header("Location: /?xyz=loggedout"); break; case 'refresh': dbUpdate("UPDATE acctussessi SET acctussessi_time = ".time()." WHERE acctussessi_unid ='".$token."'"); break; } ?> dbDelete isn't being called inside of the TimeOut() function. The only way it works is by doing the following: <?php function timeOut(){ $_SESSION = array(); setcookie(session_name(),'',time()-4200); session_destroy(); } //CHECK FOR TIMEOUT REQUEST switch($_GET['xyz']){ case 'timeout': dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'"); timeOut(); header("Location: /?xyz=timedout"); break; case 'logout': dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'"); timeOut(); header("Location: /?xyz=loggedout"); break; case 'refresh': dbUpdate("UPDATE acctussessi SET acctussessi_time = ".time()." WHERE acctussessi_unid ='".$token."'"); break; } ?> But this is annoying and repetitive. What is going on? Thanks in advance. Similar TutorialsI am a bit desperate about this problem that I have been trying to solve for several days now. I'm trying to run a Python script from the exec() function in php. The script is called but the print job is never executed. This process has been running for several years and for no clear reason it suddenly stopped working. On my home computer, it works without any problem. In my virtual machine, nothing happens. The print() functions present in the script are well displayed by the return value received by php but the printing is not executed. The virtual machine is a test environment, in production it is also an physical machine. PHP
<?php
exec("py C:\xampp\htdocs\test\test.py", $out, $res);
echo "<pre>";
print_r($out);
echo "</pre>";
echo "<pre>";
print_r($res);
echo "</pre>";
?>
if __name__ == "__main__":
try:
filename = "C:/xampp/htdocs/test/test.pdf"
win32api.ShellExecute(0, "print", filename, None, ".", 0)
except Exception as e:
print(f "An error occured during print_pdf : {e}")
The two environments are approximately the same: I'd like to point out that running the script directly from the CLI works on both machines. On the problematic machine, exec() only returns the result of print(..) I already opened a thread a few months ago about this problem but received no response.
Thank you in advance. Ok, starting around line 137 with the functions..... Commented well. Just not sure If im doing it right. Any help greatly appreciated. Basic stuff and still learning. Just trying to figure out if Im passing by reference correctly or if not how to do it. Thanks. php File is attached but heres a snippet. Thanks in advance. Peace, Adam // The grand total and the item total need to be passed BY REFERENCE. function show_table_contents($cart_items, $table, &$grand_total, &$item_total) Im trying to understand the code below. (taken from an O'REILLY book) Im trying to get my head around this, so can anyone tell me if im thinking about this in the right way; The function (fix_names) borrows the values from $a1,$a2 and $a3 and puts them into $n1,$n2, and $n3. It then processes the strings contained within these newly created variables and then returns the processed values back into $a1,$a2,and $a3? The variables $n1,$n2, and $n3 cannot be echoed as they were created within the function.? Please correct me if im wrong. Code: [Select] <html> <head> </head> <body> <?php $a1 = "EDWARD"; $a2 = "thomas"; $a3 = "wriGHT"; fix_names($a1,$a2,$a3); echo $a1." ".$a2."

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 I have the following query where $userid is about 100,000 userids separated by commas. Code: [Select] <? $getpostid=mysql_query("SELECT DISTINCT post.username,post.threadid,thread.threadid,thread.forumid from post,thread WHERE post.username='$username' AND post.threadid=thread.threadid AND post.userid IN ($userid) AND thread.forumid IN ($forumids)") or die (mysql_error()); ?>can i just print all the usernames from above result separated by ';' without looping it multiple times? Could someone help me out how to do above in an efficient manner? I am trying to use some php code inside of an html document and it does not work. I have a script.php file that executes perfectly when I try and use it. Here is the code I am currently using: Code: [Select] <?php echo "<title>"; echo "the Homepage!"; echo "</title>"; ?> Any suggestions would be great. I'm tired and want to sleep so my mistakes are getting lots now. Anybody awake that can explain my problem with the code below. <? function directoryToArray($directory, $recursive) { $array_items = array(); $i = "0"; if ($handle = opendir($directory)) { while (false !== ($file = readdir($handle)) && $i < "3") { if ($file != "." && $file != "..") { if (is_dir($directory.

Thank you for your help! Hey guys! My current employer contracted someone to create a script for him. (The script itself is to create a serial number for a piece of software) It's just a PHP script that executes a file and retrieves its output. Now I've never worked with exec() in PHP, and I don't have a reliable environment to test it in. I compiled apache2 and php 5.0.4 and set them to run on a Macintosh (10.3.9) in the office, but I'm sure I've missed some crucial setup stage (mainly, I'm missing php.ini. I did a php -i | grep php.ini to find it, and it says it is in /etc/, but when I look in my PHP/etc folder, only pear.conf is there!). PHP and apache both appear to be working fine, though. When I try and run the PHP script that executes the .ELF file, I get a blank page. Is this because I'm running it in OS X? should I be running it in Linux? Also, I don't know how to Enable exec() on my server, or to see if it's enabled. Basically, I just need someone to walk me through the basics of this. The script and executable SHOULD work fine because the contractor got it working fine. Below is the script, and attached is the executable. Thanks! :3 <?php /* inUID = 456890 inSerialNumUID = 123456 inMachineID_s = &6dA-8P@K-Xsq */ $p1 = "456890"; $p2 = "123456"; $p3 = "\&6dA-8P@K-Xsq"; exec("./create_activation_code.elf $p1 $p2 $p3", $output); foreach ($output as $output_str) { echo $output_str."<br>"; } ?> I am playing around with php but the script doesnt execute to the last point and with no error...
What i am trying to do is checking the input of the user and comparing it what is in db and then applying conditions. So i have 2 files. update.php and home.php. home.php is my html form page and i included 'update.php' in it In my update.php, i have these codes
<?php
error_reporting(E_ALL);
include_once('database.php');
if(isset($_POST['submit']))
{
$q = $_GET['q'];
$next = $q + 1;
if($q == 26)
{
echo '<h2>You have Completed the Exam.Congrats!!</h2>';
}
elseif($q <= 25){
$sql = "SELECT * FROM Students WHERE Email=?";
$stmt = $conn->prepare($sql);
$stmt->bind_param('s', $_SESSION['login']);
$stmt->execute();
$result = $stmt->get_result(); $row = $result->fetch_assoc();
$Mark = $row['Mark'];
$Correct = $Mark + 1;
$Fail = $Mark + 0;
$sqlb = "SELECT * FROM Answers WHERE qid = ?";
$stmtb = $conn->prepare($sqlb);
$stmtb->bind_param('s', $q);
$stmtb->execute();
$resultb = $stmtb->get_result();
$rowb = $resultb->fetch_assoc();
$Answer = $rowb['Answer'];
$Pick = $_POST['ans'];
if($Pick == $Answer)
{
$sqld = "UPDATE Students SET Mark=? WHERE Email = ?";
$stmtd = $conn->prepare($sqld);
$stmtd->bind_param('ss', $Correct,$_SESSION['login']);
$stmtd->execute();
$resultd = $stmtd->get_result();
echo "correct" ;
}
}
else
{
echo 'Ate';
echo "<script type='text/javascript'>document.location.href='home.php?q='.$next.';</script>";
}
}//post submit
?>
The else statement doesnt run. so it keeps reloading the same page. Also i want to ask why i keep getting the value of 2 for my $Correct variable stored on the database into column Mark for a single correct question instead of 1. What could be wrong? Lastly, i dont want the script to run if the browser is edited by the user by changing the value of $q from the browser, because i am using get method, is there a way to do that. Please be nice with your comments. Thanks in advance.!!! Hi, I am using cpanel, where i am want to run a php file, to delete the old records, i used cronjob in cpanel to do this. In time columns i have made : * * * * * to execute each and every minute the script.. In the command textbox i have made: /home/server25/public_html/auto_cancel.php in the email box: admin_email@gmail.com I am getting Permission denied to my email address: The error report am getting is : /bin/sh: /home/server25/public_html/auto_cancel.php: Permission denied Please help me to solve this. Thanks, Hi all,
This is just an experiment to make sure that I can get data from a Stored Proc 'IF' and when I need to, so it's basically a THOUGHT EXERCISE.
MSSQL 2014
I'm a noobie and need a hand, I've managed to get my Instance connected to the internet and I can query it using PHP and SQL, I can also look at views with no problem.
I have it working as an "ADODB.Connection" and like I said it connects and I can query data and display results.
Now I have coded a Stored Proc "GetMonthDays" in Sql Server:
Which returns days 1 through xxx in a given month and also returns the Day name eg... Sat for each date
2014-01-01 Thurs
2014-01-02 Fri
etc...
It works perfectly and very fast so All cool with that side BUT...
I want to be able to query the Database through a Stored Proc, I've spent all day trying to find a way to get this to work and I've hit a wall
Can anyone please tell me IF it's A. possible and B. maybe if they are really really nice and share with me a code example that I can change to fit my needs ?
This T-SQL returns what it needs to
Begin EXEC dbo.qselGetMonthDays '2015-01-01' End Cheers JD Edited by juddadredd, 02 January 2015 - 04:55 PM. Hello all, I have been working with PHP for almost a year now, so somewhat still new to it all. OK, this may be an Apache issue, but this involves a php script I wrote that tries to execute on pages that do NOT call it (via the include command). So, here is a little info on how I have set things up. I use WAMP Server to test php and MySQL code for myself (for fun and for practice) and for clients and their web sites. I run WAMP Server off of my laptop, so I can code on the go and because it is on my laptop, I decided to create a PHP & MySQL user authentication setup to keep out unwanted visitors, but allow trusted friends and fellow developers to view my work on client web sites. Let's say the authentication script is called "auth.php" and for all of the pages I want private, I include that script at the top of those pages, if the visitor is not logged in, redirect them to the login page, otherwise, let them view the page (provided their permission level is adequate). Now, for the client web sites that I am working on, I do not call auth.php anywhere on those pages. Now, the problem I notice is that when I visited a client's web site that I am working on (on my WAMP Server), I reviewed my Apache error log and it gave me a PHP error stating the following: Code: [Select] Maximum execution time of 60 seconds exceeded in E:\\wamp\\www\\assets\\auth.php on line 3, referer: http://192.168.1.4/Web_Projects/NCCCLP/home.php Of course I am able to view the client web site pages without having to login, however, the auth.php script tries to run nonetheless. So my question is, does anyone know why this is happening and if and how I can stop it? This is not a serious (urgent) issue, but it does clog up my error logs and so forth and I prefer to have as few errors as possible. Plus, I would just like to know why and how it is running without being called. Any and all help is greatly appreciated and if I need to provide anymore details or be more specific, please let me know. Also, if an issue like this has already been solved and I missed that thread, please let me know and have my apologies. Thanks in advance. Hi guys, im having a problem, in my phpfile were is generated the action code form the contacts form is giving me a lot of trouble, im receiving a lot of blank emails, first i thiked was bots,im usign a captcha, but then i notice another thing, when i put the name of the file that generates the action in the browser this loads it and send it the black email. How can i prevent for my php action file to dont be loadit in the browser? Here is the code to you guys have a idea <?php $datahora = "DATA: <B>" . date("d/m/y - H:i:s") . "</B><BR><BR>"; foreach ($_POST as $campo => $valor) { if (($campo == 'imageField2_x') or ($campo == 'imageField2') or ($campo == 'imageField2_y') or ($campo == 'distrito') or ($campo == 'subimit_y') or ($campo == 'codigo') or ($campo == 'seguranca')) {}else { if ($valor <> '') { $campo = str_replace("_", " ",$campo); $campos .= strtoupper($campo) . ": <b>" . $valor . "</b><Br>"; } } } $www = "WWW.USA.COM"; $assunto = "CONTACT - USA - " . $www; $conteudo = "CONTACT - USA<br><br>" . $datahora . ($campos) . "<br>" . $www; $para = "madness@hotmail.com"; $headers = "MIME-Version: 1.0\n"; $headers .= "Content-type: text/html; charset=iso-8859-1\n"; $headers .= "From: USA <info@usa.com>\r\n"; $headers .= "Reply-To: ".$_POST['email']."\r\n"; if ($_POST['codigo'] == $_POST['seguranca']) { if (mail($para,$assunto,$conteudo,$headers) == true){ ?> <script> alert('Sent sucess!'); window.location = 'contact.php'; </script> <? }} ?> Hope for some help [About the code] Basically what I have is a web page that de-codes a complex XML document, and displays it as a table. This is working successfully. One of the columns in the tables displays a "rank" of an object as a number (0-9). This is working successfully. What I did was write a code that would translate that rank number into a specified text, depending what number it was. [The Code] (This is only the partial code with the problem in it, the entire code of the page is very extensive.) Code: [Select] $RankNum = "{$Member->Rank}"; // {$Member->Rank} successfully displays the rank number on it's own. Below 'should' translate that number into the name of the rank. if('$RankNum' == 0) { echo('test1');}; if('$RankNum' == 1) { echo('test2');}; if('$RankNum' == 2) { echo('test3');}; if('$RankNum' == 3) { echo('test4');}; if('$RankNum' == 4) { echo('test5');}; [The Problem] All this code keeps displaying "test1" for every value in the entire column, regardless if it equaled 1 or 2 or higher... I know this has to be some simple coding mistake, but I've been sitting here for an hour trying to figure out what I had done wrong. Thanks in advance :) i'm creating a small app for someone who wants to control the content of each page from a DB. effectively it'd be a template file with header, footer, etc all pre-built, and the content area supplied from a TEXT field in a MySQL table - basically the same idea wordpress uses. this is all fine, but a couple pages would require some php - e.g., a list of events or users or articles, whatever, that are managed in different tables. i can do this with eval - something like: Code: [Select] function render_content($string) { ob_start(); eval("?>$string<?php "); $returns = ob_get_contents(); ob_end_clean(); return $returns; } but i wonder if there's a better way. i can probably limit whatever code needs to be executed in include files, so i thought maybe include some arbitrary tag and use regexp to parse it out... maybe modeled after a conditional comment, e.g., Code: [Select] <!--[include]some-file.inc.php--> // or even... <include>some-file.inc.php</include> but, again, not thrilled with the approach, and wondered if anyone had a better idea. i should probably mention that it's not going to be a "content or include" setup - it probably won't be one or the other, exclusively, and is likely to be a mix on those pages that require it - the php might need to appear before, after, or in the middle of whatever arbitrary markup the user happens to supply, e.g. Code: [Select] <h1>This is a list of stuff</h1> <p>Some explanation lorem ipsum dolor sit ahmet.</p> <?php include('some-file.inc.php'); ?> <em>But this caveat applies to the above list.</em> <div> Something totally unrelated. <img src="pic.jpg" /> </div> not sure I explained that very well, but hopefully the concept comes across. TYIA Hi All Basically I have 4 fields in my database image2, image3, image4, image5 I have an image uploader to upload the files but I need what I need is if image2 is empty put in image3, if image3 is empty put in image4 so far I have this //so first is the query to find the right row which gives the variable $row //now here is what im doing if($row['image2']!==""){ //run this code } elseif($row['image3']!==""){ //run this code } elseif($row['image4']!==""){ //run this code } elseif($row['image5']!==""){ //run this code } Now the problem I'm having is the code that is always executing is the first one of $row['image2'] even if image2 has a value in the database it still runs that code and over writes the field in the database. It never moves on to field 3 or 4. Can someone please tell me if I've done something wrong. I'm not storing the image in the database just the name. Thanks Danny In my php web program I'm trying to execute a bash shell script on the web server passing to it some parameters gathered within the program. Ideally I wouldl ike to run this script as another user. However, I get only a return code of "1" and no other error messages that I can see. I tried using system and passthru as well and I'm sure the script is executable by anyone. I've also tried the sticky bit on the target shell script. Can someone/anyone please provide some gotcha pointers about doing this? As can be expected, after playing with this for a week now I'm extremely frustrated and nearly exhausted my resources (except for this forum). Ideas/suggestions please? Thanks I have a PHP application where I am trying to execute a PHP routine when the user clicks on a link to go to another page. The routine needs to execute before I use a header location command to send the user to the next location. I can't do this all with JavaScript, but it could be part of the solution if necessary. I'd prefer to just use PHP if I could, but I'm not sure that this is possible. Can anyone share with me a brief example of how I could do this? Thanks! |
