PHP - Include Code Works On One Page But Not Another

I want to include a variable (for example an object $user) in each PHP page.

Previously I declared $var in an include file then included that file in every page, however it generates an error in Zend Studio and it's also not very good programming style.

I want to know how I can do it any other way.  I was thinking of using constants but I don't know if constants should be used for this purpose and also I do not think constants can be defined as objects.

Thank you very much for your help.

Hi all

not been playing with php over the past year and still a noob lol

i did have some code to include files based on the URL link

E.G:
Code: [Select]
http://www.yoursite.com/index.php?page=about
then i had some form of string that would access the URL

so it would have checked if the url was just index.php or had ?page=somepage after it

I can not seem to find any referance on the www or shift the headach i have got trying to remember the code

so thought some of you wondaful people would no what i am on about and point me in the rught direction of a tutorial for the information or have the code tohand so i can referance from it


thanx all

Greetings to all!

Newbie here, I just signed up this morning. I have an issue with a code I have been using for several years with multiple files/directories. Until recently all of the files have worked flawlessly. Now I have one file in a directory that does not display the text I which I am attempting to call up and it was working until recently.

As stated above I have the same code in multiple directories and files and it works flawlessly in all files except for the one. I have spent a few hours attempting to remedy the situation with no success. I have looked at the source code for the errant file and that shows the text to be displayed but it is not displayed in any browser on several computers, whether Windows or Mac OSX. I even went so far as to delete the directory the file was in and re-uploaded the entire directory from a backup that is 2 or 3 years old, no change. I copied the entire coding from a working file with the same coding, deleted all the coding in the errant file and pasted the working coding into the errant file. - no change

I have attached screen shots of the coding in errant file and one of many other files that work flawlessly with the php code that is involved highligted. Also attached are the browser page source files for the same errant and working files. The screen shots in order are errant file code, working file code, errant file source, and working file source.

Every file with the same code as the errant one work flawlessly except for the errant one, and I have 11 files to be displayed on my website at https://TheLoveOfGod.org They are all listed under the Devotionals menu button except for one which is displayed on the home page. I have absolutely no training in web design, I am self taught. I began by hand typing html coding over 30 years ago and am now using Word Press with Elementor . I do not understand why this is happening. Can any of you offer assistance to resolve this. I thank you in advance for your assistance.

Respectfully,
dan

Hi,

I'm having a first attempt at sanitising code, but I'm not actually sure what I'm doing and how I know if it works.

This is the code I have inserted, if I enter "description=re#d%widget" the description query ends so it displays everything 'red'.  Not just everything 'red widget'.


Code: [Select]
$description = mysql_real_escape_string($description);
$description = stripslashes($description);
$description = htmlentities($description);
return $var;

$price = mysql_real_escape_string($price);
$price = stripslashes($price);
$price = htmlentities($price);
return $var;




Code: [Select]
<?php

ini_set('display_errors', 1);
error_reporting(-1);



$query = "SELECT * FROM productfeed";

if(isset($_GET['description']) && !empty($_GET['description']))
{
$description = $_GET['description'];
$query .= " WHERE description like '%$description%'";
}

if(isset($_GET['price']) && !empty($_GET['price']))
{
$price = explode('-', $_GET['price']);
$lowPrice = (int)$price[0];
$highPrice = (int)$price[1];

$query .= " AND price BETWEEN $lowPrice AND $highPrice";
}


$result = mysql_query($query);

while($row = mysql_fetch_assoc($result))

{

$id = $row['id'];
$image = $row['awImage'];
$link = $row['link'];
$description = $row['description'];
$fulldescription = $row['fulldescription'];
$price = $row['price'];

echo "<div class='productdisplayshell'>
<div class='productdisplayoutline'>
<div class='productborder'><center>
<a href='$link' target='_blank'><img src='$image' width=\"95%\" /></a>
</center> </div></div>
<div class='productdescriptionoutline'>
<div class='productdescriptionbox'>
<a href='$link' target='_blank' >$description</a>
</div>
<div class='productfulldescriptionbox'>$fulldescription</div>
</div>
<div class='productpriceoutline'>
<div class='productpricebox'>
<center>&#38;#163; $price</center>
</div>
<div class='productbuybutton'>
<center><a href='$link' target='_blank' ><img src=/images/buybutton.png /></a></center>
</div>
</div>
</div>";
} 

if ($_GET['description'] == $description ) {
echo 'Sorry, this product is not available.  Please visit our <a href="http://www.domain.co.uk">Homepage</a>.';
}


?>

<?php
function sanitizeString($description)
{
$description = mysql_real_escape_string($description);
$description = stripslashes($description);
$description = htmlentities($description);
return $var;

$price = mysql_real_escape_string($price);
$price = stripslashes($price);
$price = htmlentities($price);
return $var;


}
?>

I have some code that works fine on my dev server but does not work on my production server.  Dev server has PHP version 5.2.5 and production server has PHP version 5.1.6.

This is the part of the code that isn't working on the prod. server:
$xmlDoc=new DOMDocument();
$xmlDoc->loadXML($tmpDoc);

$x=$xmlDoc->getElementsByTagName('link');

//get the q parameter from URL
$q=$_GET["q"];

//lookup all links from the xml file if length of q>0
if (strlen($q)>0)
{
$hint="";
for($i=0; $i<($x->length); $i++)
{
$y=$x->item($i)->getElementsByTagName('title');
$z=$x->item($i)->getElementsByTagName('url');
if ($y->item(0)->nodeType==1)
{
//find a link matching the search text
if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q))
{
     if ($hint=="")
     {
     $hint="<tr><td><a href='" .
         $z->item(0)->childNodes->item(0)->nodeValue .
        "' target='_blank'>" .
        $y->item(0)->childNodes->item(0)->nodeValue . "</td></tr>";
     }
     else
    {
     $hint=$hint . "<tr><td><a href='" .
         $z->item(0)->childNodes->item(0)->nodeValue .
         "' target='_blank'>" .
         $y->item(0)->childNodes->item(0)->nodeValue . "</a></td></tr>";
     }
}
     }
   }
}

$tmpDoc is a variable that holds database information in xml form.  It basically looks like this:
$tmpDoc = $tmpDoc . "<link><title>" . $row['CustomerName'] . "****" . $row['Rep'] . "****" . $row['InstallDate'] . "****" . $row['PaidDate'] .  "</title><url>accountPage.php?AccNum=" . $row['AccountNum'] . "</url></link>";

...that is inside a while loop that loops through the rows returned by a query.

Basically, as I said, the whole thing works fine on my dev server but on the production server it never makes it into the for loop so I guess the condition $i<($x->length) isn't being met.  I'm at a bit of a loss here.  Is there anything like the PHP version or Apache version that may cause the "->" operator to not work?  The prod PHP version isn't that much older than my dev PHP version so I doubt that's the issue but it's about all I can think of.

Thanks!

Hi all, Having an issue with some of my php code. The goal is to have two drop-down menus, one that pulls from "ahevents_scenarios". The second pulls the "sides" involved, however it does not go into dropdown. The other issue is that even though there are only 3 sides specified, all 5 show up on the webpage. This is in Joomla.     Here is my code...I think I've looked over this way too much and just can't find my errors anymore.

<?php



if (! $my->id) {

  // shouldn't even get here since menu is viewable only through logged in status

print "<b>Sorry, you must be registered and logged into this site to continue</b>\n";

}

else {



// include standard functions and db info

require_once($_SERVER['DOCUMENT_ROOT'] . "/inc/admin_functions.php");

require_once($_SERVER['DOCUMENT_ROOT'] . "/inc/db_admin_functions.php");



// which scenario we doing?  -- replace with table lookup in future



opendb('ahevents_scenarios');



if(!isset($_POST['action'])) { // display form

    $sqlstr2 = "select id, name from scenarios order by name";

    $result2 = mysql_query($sqlstr2) or die("Error: ".mysql_error()."<br>Query: $sqlstr2");

  // display form

?>



<form name="edit_reg" method="post" action="<? echo $_SERVER[ 'REQUEST_URI' ]; ?>"

<table>

<tr>

<td>Select Scenario: </td>

<td>

<select name="id">

<? while ( $row = mysql_fetch_array($result2)) {

    printf("<option value=\"%s\">%s</option>\n",$row['id'], $row['name']);

}

?>

</td></tr>

<tr>

<td>Which Side?</td>

<td><select name="side">

<option value="side_1">side_1</option>

<option value="side_2" >side_2</option>

<option value="side_3" >side_3</option>

<option value="all" selected>All</option>

</select>

</td></tr>

</table>

<p>

<input type="submit" name="action" value="Get Registrants">&nbsp;

<input type="reset" value="Reset">&nbsp;

<input type="button" name="" value="Back" onClick="history.back()">

</form>

The goal is to download the registrants into a .csv file, which it does, however due to not being able to select a "side", the .csv is blank with only headers, no content.   Thanks for your time Rob

Is there some way of a php include which is visible on every page (footer), itself having two php includes, but only one of which would be visible, then on the user refreshing the page or on visiting another page on the site, that include would be replaced with another php include?  Preferably done without any js.

Any help appreciated.

I am trying to force home landing page text onto this wordpress themes (weblizar Enigma)  standard page (which doesnt seem to allow for this even with settings/reading/static/home page option selected wordpress settings) The landing page just seems to be wigitised.    In a nutshell, I want to have a "page" of text on home page below banner slider and instead of "BLOG" and blog text. Hope this makes sense. Not getting help from theme author and I have been pointed towards .phpfreaks This is the website below.... http://www.cloudchasing.co.uk Thankyou in advance guys

Hello, 

I'm new on this forum and i have not seen the rules to post a code, so i will try to explain my best :

I have learned the basics of php during the past few days and i have a php code that is supposed to read parameters in several fields of a Mysql database and to return those parameters as variables in an array. (well that's how i understand it... please correct me if i'm wrong)

So here the code and the part that doesn't seem to work properly (colored in red) :

 //I have changed the following values which are confidential...
 $DBName = "MyDatabase";
 $DBHostName = "MyMysqlServer";
 $DBUserName = "MyUsername";
 $DBPassword = "MyPassword";
 $Table = "MyTable";
 //The fields which are in MyTable :
 // MemberID SMALLINT
 // MemberName VARCHAR(20)
 // MemberPassword VARCHAR(20)
 // MemberEmailAddress VARCHAR(50)
 // MemberDateTimeInscription VARCHAR(19)
 //Reading member parameters
  echo"<br>Reading the parameters of a member.";
  echo"<br>Defining the parameters of the member to read.";
  $CurrentName = "Ashley";
  $CurrentPassword = "65hl3y";
  $CurrentEmailAddress = "Ashley@HisDomain.com";
  echo"<br>Trying to start a connection with the Mysql server.";
  mysql_connect($DBHostName,$DBUserName,$DBPassword) OR DIE(mysql_error());
  echo"<br>Selecting the table.";
  mysql_select_db($DBName) OR DIE(mysql_error());
  echo"<br>Searching for the fields corresponding to the CurrentName.";
  $Query = "SELECT * FROM ".$Table." WHERE MemberName = '".$CurrentName."'"; 
  $Result = mysql_query($Query) or die(mysql_error());
  echo"<br>Returning the parameters stored in the fields.";
  while($Row = mysql_fetch_array($Result,MYSQL_ASSOC)){
   /////This is the start of the part that does not seem to work properly.
   $MemberId = $row["MemberId"];
   $MemberName = $row["MemberName"];
   $MemberPassword = $row["MemberPassword"];
   $MemberEmailAddress = $row["MemberEmailAddress"];
   $MemberDateTimeInscription = $row["MemberDateTimeInscription"];
   echo"<br>MemberId : ".$MemberId;
   echo"<br>MemberName : ".$MemberName;
   echo"<br>MemberPassword : ".$MemberPassword;
   echo"<br>MemberEmailAddress : ".$MemberEmailAddress;
   echo"<br>MemberDateTimeInscription : ".$MemberDateTimeInscription;
  /////This is the end of the part that does not seem to work properly.  
  }
  echo"<br>Ending the connection with the Mysql server.";
  mysql_close();


All of echo are here for debug, i'm a beginner with php.

This is what the php page shows :
Reading the parameters of a member.
Defining the parameters of the member to read.
Trying to start a connection with the Mysql server.
Selecting the table.
Searching for the fields corresponding to the CurrentName.
Returning the parameters stored in the fields.
MemberId :
MemberName :
MemberPassword :
MemberEmailAddress :
MemberDateTimeInscription :
Ending the connection with the Mysql server.

I don't understand why the variables $MemberId, $MemberName, $MemberPassword, $MemberEmailAddress, $MemberDateTimeInscription are empty.

Your advices are welcome,
Thanks,

When i want to implement it in my signup page, it doesnt do anything. I've checked it a thousand times, i double checked that also the

-formname of my signup page is 'formname'
-the element name stays 'subcategory'

I really need this to be implemented. Where can be the problem? What should i look for?

Hi,

I have some code which works but when I created a function and call this same code it doesn't. The error I get is as follows:

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /home/fhlinux010/l/languageschoolsuk.com/user/htdocs/admin/email.php on line 42
Error retrieving schools

The code
function CreateSchoolCheckboxes()
{
echo '<div style="height:400px;width:400px;font:16px/26px Georgia, Garamond, Serif;overflow:scroll;">';

$querySchools = "SELECT * FROM school";
$result = mysql_query($querySchools, $conn)
or die ("Error retrieving schools ".mysql_error());

while($row = mysql_fetch_array($result))
{
$schoolname = $row['name'];    
echo '<input type="checkbox" name="school" value="'.$schoolname.'">';
echo $schoolname . '<br>';
}      

echo '</div>';
}

Im sure that this is probably something simple but any suggestions would be much appreciated.

Thanks,
Joe

I have made a bit of code that queries the database for articles published within the last year.

<?php echo $numposts = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->posts WHERE post_status = 'publish' AND post_type = 'post' AND 'post_date' > '" . date("Y") . "-01-01-01 00:00:00'");
if (0 < $numposts) $numposts = number_format($numposts); ?>

I really don't even know how it works and need to because I want to figure out how to make it also get articles published within the last day, month and week.

I suppose if I understood what needs changing I might be able to work with it but so far everything I've tried either returns the exact same number or nothing at all.

It's for Wordpress just to note.

Any ideas?

I have 2 websites, a companies main website written in PHP and a web application they have purchased written in aspx

(main site)
www.example.com

(web app)
www.webapp.com/login.aspx?CompanyName=example

The client wants people to be able to login from their main website which then redirect to the webapp (which will be styled like their branding) without the customer realising they have left the main site.

I thought i may be able to achieve this with a simple include from a page within the main site such as;
Code: [Select]
<?php
// www.example.com/software

include"http://www.webapp.com/login.aspx?CompanyName=example";
?>
This pulls in the login page fine, however when you try to login it does not redirect, it gives a 404 error as it trys to open this URL
http://www.example.com/software/login.aspx?CompanyName=example

Is there a way of pulling in the necessary html from the aspx site to provide a login box in my clients main site but then have it redirect to the correct aspx page (on the aspx site)?

I have thought about using an iframe, but that wont redirect to the webapp upon login, but just keep everything withing the iframe

thanks for any advice...

Hi,

Please bear with me, I have no real experience with PHP but am using it for the first time in a page for maintenance purposes.

One of the things I am trying to do is include a random page from within a certain folder (folder: 'modules/did-you-know').  Inside this folder there are currently three files named in this format 'did-you-know-###.php' - where ### is the page number.

I have no problems including the named page individually, but it is when randomising it where it causes errors.

The code I am using is the following:

Code: [Select]
<?php
            $i=0;
$myDirectory = dir("modules/did-you-know");
while($file=$myDirectory->read())
{
$array[$i]=$file;
$i++;
}
$myDirectory->close();

$num = count($array);
$random = rand(0, $num);

include "$array[$random]"; ?>

When I load the page, I get numerous errors, as follows:

Warning: include(..) [function.include]: failed to open stream: Operation not permitted in /home/{USERNAME}/public_html/test2/index.php on line 103

Now, it's clear from the above that it is (at least sometimes) reading the files from within the 'did-you-know' directory, so not sure why I am getting these errors. (Especially the last one, as that would suggest an error to do with permissions, would it not?)

Line 103 is the "include" line.

Any help would be appreciated.

Thanks
