PHP - Problems With Dynamic Pages

Great conversation, wrong board.

This topic has been moved to Application Design.

I got a question  regarding a news website content that i want to make ! my question is how do i   call my contents without using a lot of page?   i explain   let's say i got 10 news how do i put this 10 news in different pages without using 10 pages ? ex: you can see some links having a number like this http://bbc.uk/news/murder_case-12 then the next page got http://bbc.uk/news/finance-13 the title and the number id change but the page news doesnt change    thanks for your answer.

Most of my website is written in php4. My hosting server has support for both 4 and 5 just by changing file extension. .php which is the default supports 4, .php5 of course supports 5. The problem I am having is that the pages with the .php5 extensions are not recognizing session variables. Is there something I should be doing differently in 5 for my session variables?

For example a variable request like this returns 0

print $_SESSION['FULLNAME'];

Please Help!! Thank you in advance?

Hi,

I'm building a dynamic site for a college project (a CMS) and have been using a Lynda tutorial. When the user clicks on a subject, the sub menu appears for the (a UL with a UL), so there is an 'accordian effect'. However, when I click on one of the page links in the sub menu, the content for that page appears, but the second UL containing the links to the pages dissapears. It only re-appears when I click back on the parent element (the subject link).

I'd really appreciate some help. I've tried editing this code below but have had no joy:

Code: [Select]
function public_navigation($sel_subject, $sel_page, $public = true) {
$output = "<ul class=\"subjects\">";
$subject_set = get_all_subjects($public);
while ($subject = mysql_fetch_array($subject_set)) {
$output .= "<li";
if ($subject["id"] == $sel_subject['id']) { $output .= " class=\"selected\""; }
$output .= "><a href=\"index.php?subj=" . urlencode($subject["id"]) .
"\">{$subject["menu_name"]}</a></li>";
if ($subject["id"] == $sel_subject['id']) {
$page_set = get_pages_for_subject($subject["id"], $public);
$output .= "<ul class=\"pages\">";
while ($page = mysql_fetch_array($page_set)) {
$output .= "<li";
if ($page["id"] == $sel_page['id']) { $output .= " class=\"selected\""; }
$output .= "><a href=\"index.php?page=" . urlencode($page["id"]) .
"\">{$page["menu_name"]}</a></li>";
}
$output .= "</ul>";
}
}
$output .= "</ul>";
return $output;
}


The code that precedes this is as follows:

Code: [Select]

function get_all_subjects($public = true) {
global $connection;
$query = "SELECT *
FROM Subjects ";
if ($public) {
$query .= "WHERE visible = 1 ";
}
$query .= "ORDER BY position ASC";
$subject_set = mysql_query($query, $connection);
confirm_query($subject_set);
return $subject_set;
}

function get_pages_for_subject($subject_id, $public = true) {
global $connection;
$query = "SELECT *
FROM pages ";
$query .= "WHERE subject_id = {$subject_id} ";
if ($public) {
$query .= "AND visible = 1 ";
}
$query .= "ORDER BY position ASC";
$page_set = mysql_query($query, $connection);
confirm_query($page_set);
return $page_set;
}

function get_subject_by_id($subject_id) {
global $connection;
$query = "SELECT * ";
$query .= "FROM Subjects ";
$query .= "WHERE id=" . $subject_id ." ";
$query .= "LIMIT 1";
$result_set = mysql_query($query, $connection);
confirm_query($result_set);
// REMEMBER:
// if no rows are returned, fetch_array will return false
if ($subject = mysql_fetch_array($result_set)) {
return $subject;
} else {
return NULL;
}
}

function get_page_by_id($page_id) {
global $connection;
$query = "SELECT * ";
$query .= "FROM pages ";
$query .= "WHERE id=" . $page_id ." ";
$query .= "LIMIT 1";
$result_set = mysql_query($query, $connection);
confirm_query($result_set);
// REMEMBER:
// if no rows are returned, fetch_array will return false
if ($page = mysql_fetch_array($result_set)) {
return $page;
} else {
return NULL;
}
}

function get_default_page($subject_id) {
// Get all visible pages
$page_set = get_pages_for_subject($subject_id, true);
if ($first_page = mysql_fetch_array($page_set)) {
return $first_page;
} else {
return NULL;
}
}

function find_selected_page() {
global $sel_subject;
global $sel_page;
if (isset($_GET['subj'])) {
$sel_subject = get_subject_by_id($_GET['subj']);
$sel_page = get_default_page($sel_subject['id']);
} elseif (isset($_GET['page'])) {
$sel_subject = NULL;
$sel_page = get_page_by_id($_GET['page']);
} else {

}
}

function navigation($sel_subject, $sel_page, $public = false) {

Hi,

Having completed a site migration this am everything went well aside from issues with logging into and out of our site where two files are used and appear as white pages.

When logging into our site, proc_login.php is used and when logging out proc_logout.php is used.

Both processes result in a white "blank" page instead of the php files forwarding on.

I've no idea about php generally and have been trying my best to find useful and similar information online to attempt to resolve the problem.  I am now stuck.

The site works perfectly on my local web server, and what is really baffling me is the site also works perfectly on Domain B on the exact same server I'm trying to get the site running under as Domain A.  In other words as both Domain A & B are configured on the same host server I'm thinking all the inherited php/apache/mysql settings should be identical (or pretty much thereabouts) and therefore am more confused than ever! 

I simply don't know where to start therefore in resolving this problem.  I've tried looking in the error log file and have also played around with turning on error enabling on those specific php files to try and follow any errors, however the "errors" generated are no different than the ones present on sites where the login/logout process works just fine.

I've hopefully attached both files and if anyone could assist in helping me narrow down my search for a solution I'd be very appreciative.

Thanks.

Folks,

I need help (Php code ) to generate a Dynamic Text on a Base Image. What i want to do is, to make this Image as header on my Site and to make this Header Specific to a Site, i want to Add the Domain Name on the Lower Left of the Image.

Got the Idea?

Here is the Image link:

Quote

PHP Variable that holds the Domain name is:  $domain 

All i need the Dynamic PHP Codes that i can put on all my sites to generate this Text on Image (Header) Dynamically...

May Anyone Help me with this Please?

Cheers

Hi all

I need to combine these two scripts:

Firstly, the following decides which out of the following list is selected based on its value in the mySQL table:

<select name="pack_choice">
<option value="Meters / Pack"<?php echo (($result['pack_choice']=="Meters / Pack") ? ' selected="selected"':'') ?>>Meters / Pack (m2)</option>
<option value="m3"<?php echo (($result['pack_choice']=="m3") ? ' selected="selected"':'') ?>>Meters / Pack (m3)</option>
<option value="Quantity"<?php echo (($result['pack_choice']=="Quantity") ? ' selected="selected"':'') ?>>Quantity</option>
</select>

Although this works OK, I need it also to show dynamic values like this:

select name="category">
<?php
$listCategories=mysql_query("SELECT * FROM `product_categories` ORDER BY id ASC");
while($categoryReturned=mysql_fetch_array($listCategories)) {
echo "<option value=\"".$categoryReturned['name']."\">".$categoryReturned['name']."</option>";
}
?>
</select>

I'm not sure if this is possible?

Many thanks for your help.

class curl2{

    private $curl_init; 
    private $CURLOPT_URL;

    public function connect(){ 
       $this->curl_init = curl_init(); 
    }

    public function debug(){
 
       curl_setopt($this->curl_init, CURLOPT_VERBOSE, TRUE);
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
       curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);

    }

    public function setUrl($url = null){

    }

    }
}

$curl2 = new curl2;
$curl2->connect();
$curl2->setUrl("http://www.linuxformat.co.uk");
$curl2->debug();
echo $curl2->execute();



It display a blank page like attachment result1.jpg, but if I move the
$fp = fopen("curl2.txt", "w"); 
curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);
from function debug() and join it with function execute()
like this:
  public function execute(){
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
       curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);

       $out = curl_exec($this->curl_init);
       curl_close($this->curl_init);

       return $out;
    }

it return me Linuxformat content ( expected result ) like result2.jpg

below is the working code :
class curl2{

    private $curl_init; 
    private $CURLOPT_URL;

    public function connect(){ 
       $this->curl_init = curl_init(); 
    }

    public function debug(){
 
       curl_setopt($this->curl_init, CURLOPT_VERBOSE, TRUE);
      

    }

    public function setUrl($url = null){
       $this->CURLOPT_URL = $url;
       curl_setopt($this->curl_init, CURLOPT_URL, $this->CURLOPT_URL);
    }

    public function execute(){
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
       curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);

       $out = curl_exec($this->curl_init);
       curl_close($this->curl_init);

       return $out;
    }
}

$curl2 = new curl2;
$curl2->connect();
$curl2->setUrl("http://www.linuxformat.co.uk");
$curl2->debug();
echo $curl2->execute();

 
Why I couldn't split "CURLOPT_STDERR, CURLOPT_RETURNTRANSFER" with "curl_exec"
 

like if I'm displaying a hundred entries , my website will be super long in length so I wanna break those hundred entries into maybe like 12 per page .  Then click next page or the page number to view the next 12.

Hello everyone,

 I am new to this site and new to working with php. I am wondering about a code that i could use for splash pages for members to be able to use them. I have the splash pages set up already but have not been able to figure out how to code it so that all the members of the site can use them to promote the site.

 Any help would be great thanks.

what I'm trying to do is to setup a page called settings.php that the admin runs to order to turn option in the web site on or off. I don't know how to do this since I never done this before. My code is below.


<link href="mainframe.css" rel="stylesheet" type="text/css">

<?php
require_once '../config.php';

$db = new DbConnector();
$db->DbConnector();


if(isset($_GET['submit'])) {

$db->query('UPDATE '.SETTING_TABLE.' SET option='.$_POST['banner'].' WHERE setname=''');

  echo 'Process complete';
}

$result = $db->query('SELECT * FROM '.SETTINGS_TABLE);

echo '<table border="1">';
echo '<tr>';

echo '<form action="settings.php" methed="post">';

while($row = $db->fetchArray($result))
  {
   
  echo '<tr>';
  echo '<td>'.$row['setname'].'</td><td><select size="1" name="'.$row['setname']'">';
  echo '<option value="on">on</option>';
  echo '<option value="off">off</option>';
  echo '</td>';  
  echo "</tr>";
  }
  echo '<td><input type="submit" value="Submit" name="submit">';
  echo '</td>';

echo "</tr>";
echo "</form>";
echo "</table>";

/*
*/

?>

<h2>Settings</h2>

<a href = "admin.php">Admin Panel</a>

Hi,

I am looking for reliable, effective code to cache one or two of my website webpages. I know there are packages like the pear cache lite but is far beyond my needs and complex in terms of never used pear before etc.

I am looking for a good cache class perhaps or a link to a good cache script. Does anyone have any code they would like to share or know of any good cache classes etc?

I want to keep it relatively simple if possible.

Thanks for any suggestions, help.
