PHP - Results On Multiple Pages Help

Hi,

my page is currently up at brewhas.org/transactions.php.  When I retrieve a set of results > the defined # per page (such as entering 'WI' for last name), I see the first page correctly, and see the links to next pages, but when I go to the next page there are no results displayed.  Same for p.3, etc.

So I've looked around enough to know that I need to pass a variable to the subsequent pages, either via a session variable or the URL.  I have 2 fields input on the form, as well as a limit and offset.  My questions are 1) do I need to pass all 4 and if so then should I use a session variable so the URL does not get too long, and 2) can anyone provide any help with setting session variables and including them to be passed?

I'm a newbie and have grabbed some code where I can but this is where i'm stuck.  thanks in advance.

  In the code below, I am trying to produce a google-like page where the user can type keywords
and pages of search results are displayed.
  The main difficulty I am encountering is that when the browser changes pages, it forgets everything about current data.    Perhaps I should include the display of pages inside the HTML form ? How can I fix this code ?
   Here is the contents of my searchpage.php file :

<?php



$keywords='';
$display_search_results='';

if(isset($_POST['search_submitted'])) {
    $keywords=$_POST['keywords'];
    $search_results=array();
    $totalNbrOfItems=20;
    for($k=1;$k<=$totalNbrOfItems;$k++) {
      $search_results[$k]='Your keywords '$keyowrds.' have been found in item number '.$k;
    }  

    $nbrOfItemsParPage = 5;
    $nbrOfPages = ceil($totalNbrOfItems / $nbrOfItemsParPage);
    // Compute current page
    $current_page = (isset($_GET['page']))?intval($_GET['page']):1;
    $display_pages=($nbrOfPages<2)?'<p>Page : ':'<p>Pages : ';
    for ($i = 1 ; $i <= $nbrOfPages ; $i++)
    {
        if ($i == $current_page) //No link to the current page
        {
            $display_pages=$display_pages.$i.' ';
        }
        else
        {
            $display_pages=$display_pages.'<a href="searchpage.php?'.
            'page='.$i.'">'.
            $i . '</a> ';
        }
    }
    $display_pages=$display_pages.'</p>';
    $display_items='';
    $start=$nbrOfItemsPerPage*($current_page-1);
    for($k=1;$k<=$nbrOfItemsParPage;$k++) {
      $display_items=$display_items.($search_results[$start+$k]).'<br>';
    }
    $display_search_results=$display_pages.$display_items;
}


echo '<form method="post" action="searchpage.php">'.
' Type your keywords here : <br><br>'.
'<textarea cols="65" rows="1" '.
'id="keywords_id" name="keywords">'.$keywords.'</textarea>'.
'<input type="submit" name="search_submitted" id="search_submitted_id" value="Search" /> '.
'</fieldset>'.

HY

I have index.php and pictures.php.
In index.php I have 3 columns:
- left (for menu)
- right (for advertising)
- center (where I want to include pictures.php)

What is the best way to include pictures.php in center of index.php

Code: [Select]
if($_get[pictures]){
include ("pictures.php");
}

I ask this because I have multiple variable like "pictures" and I will have multiple "If".

Or to include in DB all this variables "pictures" and just add ".php" extension. It is secure in this way ?

Thanks

Hey guys, how is everyone today?

I am needing a little help with this one. I have a database that updates itself and the display page for it with every form submission on the website. I am wondering how I go about getting it to display across multiple pages? For example, once it hits 25 submissions, it would make a page 2, once page two hits 25 submissions, it creates page 3, etc. etc. Much like you see on something like a forum, it hits so many replies before it creates a new page, to limit one long page of results.

Thanks in advance!! 

Hello.

I'm coding myself an small webpage, In the internet you can see that there is pages like index.php?id=223923 <- for example or index.php?=news.
 So, I'm trying to create similar to that myself. I tried googling and searching youtube how to do this but didn't really find anything.

I figured it out that it needs some database etc.

I tried myself doing some table in my mysql db. And in the table some 'id, title, content' and in the id would be the url, (index.php?='id') the title would be the <title> </title> and the content would be all the code inside the webpage. I got no idea how to link these to an php or whatever it should be done So would anyone kindly tell me howto do this or give some link to an tutorial?

Hi guys,
 I have a php file that will go to a site and scrape the data I need. However this site is setup to use pagination so when I try to scrape all the players names I have to do separate queries to search each page. Is there a way to find out by using code how many pages there are and query all the pages at same time?

I use  this code
Code: [Select]
<?php //first page

//turn error reporting on
libxml_use_internal_errors(true);

//get data from this page
$dom = new DOMDocument;
$dom->loadHTMLFile('http://www.gametracker.com/server_info/76.73.3.42:1716/top_players/?searchipp=50#search');
$xpath = new DOMXPath($dom);

// Get the total player count
$rows2 = $xpath->query('//div[@class="block774"]/div');

// Get the rows from the search list
$rows = $xpath->query('//table[@class="table_lst table_lst_spn"]/tr');


for ($i=1; $i<$rows->length-1; $i++) {
    $row = $rows->item($i);

    // Get the columns for a row
    $cols = $row->getElementsByTagName('td');

// Get the player rank (1st column)
    echo 'Rank:'.trim($cols->item(0)->textContent).PHP_EOL;

    // Get the player name (2nd column)
    echo 'Name:'.trim($cols->item(1)->textContent).PHP_EOL;

// Get the player score (3rd column, actually 4th but number 3 is hidden)
    echo 'Sco '.trim($cols->item(3)->textContent).PHP_EOL;

echo "<br />";
}
?>





<?php //secondpage

//turn error reporting on
libxml_use_internal_errors(true);

//get data from this page
$dom = new DOMDocument;
$dom->loadHTMLFile('http://www.gametracker.com/server_info/76.73.3.42:1716/top_players/?searchipp=50&searchpge=2#search');
$xpath = new DOMXPath($dom);

// Get the rows from the search list
$rows = $xpath->query('//table[@class="table_lst table_lst_spn"]/tr');


for ($i=1; $i<$rows->length-1; $i++) {
    $row = $rows->item($i);

    // Get the columns for a row
    $cols = $row->getElementsByTagName('td');

// Get the player rank (1st column)
    echo 'Rank:'.trim($cols->item(0)->textContent).PHP_EOL;

    // Get the player name (2nd column)
    echo 'Name:'.trim($cols->item(1)->textContent).PHP_EOL;

// Get the player score (3rd column)
    echo 'Sco '.trim($cols->item(3)->textContent).PHP_EOL;
echo "<br />";
}

?>
I also have to go to that website first to see how many pages there are so I can have enough queries.

I am creating a webpage for my golf league and some of the information(variables) such as Name, Address and email, must be reused across multiple pages for different outputs.  May question is "Can I, or is there a way to reUse variables across multiple pages.   "Do I need to create a session and make everything session variables"?  "Should I link to a database and call the information when needed"? 

Any explanation would be greatly appreciated. 

Hey Im always trying to remove code and cut corners to reduce work in the long run, soIim wondering how I could link my menu bar from say a template to ALL my php pages for my site so I don't have to write/change links on every page when I need to.

Thanks

I have an ordering process that consists of 3 pages:

1) Page1: Enter name/address
2) Page2: Based on address, determine availability of products, and let user choose which products, how many, etc.
3) Page3: Enter credit card info to send to the processor

What is the best way to store information fro page 1 to page 2, then from page 2 to page 3? I thought about just using hidden fields. Is this OK? Is there another preferred way?

Thanks!

Hi,

I have some code which scrapes data from a page. However there are around 1200 product pages on the site I need to scrape, when I attempt to loop through all the pages I get a server timeout. I can only get to around 40 without timeout. Has anyone else had this problem?

I'm am somewhat new to PHP and am trying to set up a website for my cousin's wedding. Her idea is to have the guests sign in with a user/pass that she provides, and once they sign in, they will be taken to a page that has their name on it (i.e. "Mr. and Mrs. So and So, you are invited...). I have come to the conclusion that I will need to make an image for each guest's name (she wants to use a font for their names that nobody will have on their computer) so what I need to know is:

How do I link each user name to their own personalized webpage, where the image of their name on the next page will change based on what username is entered? I have been told to use Sessions (which I don't yet have in this code), but I'm clueless as to how to make that work for multiple users. Where do I put the coding, what does the coding look like, etc.

Thanks in advance for any help!

The php code I have right now is this (i'm sorry it's so long, I just don't want to leave anything out that might be important):

Code: [Select]
$LOGIN_INFORMATION = array(
  'steve' => 'password',
  'rick' => 'password',
  'tom'=> 'password'
);

// request login? true - show login and password boxes, false - password box only
define('USE_USERNAME', true);

// User will be redirected to this page after logout
define('LOGOUT_URL', 'http://www.example.com/');

// time out after NN minutes of inactivity. Set to 0 to not timeout
define('TIMEOUT_MINUTES', 0);

// This parameter is only useful when TIMEOUT_MINUTES is not zero
// true - timeout time from last activity, false - timeout time from login
define('TIMEOUT_CHECK_ACTIVITY', true);

Hi all,

I've done a LOT of googling on this and found things that match what I need but nothing actual achieves what I need.

I've used one php file before for doing multiple jobs (ie registration?step=2 / 3 etc), but I've boo-booed somewhere and it only works up until step 2, step 3 doesn't work.  Here's what I have currently, it also leads me on to the next question.

Code: [Select]
<?php if(isset($_GET['step']) == 2) { ?>
   Please select the problem you are encountering.
   <a href="registration.php?step=3&console=<?php $_GET['console'] ?>&issue=1rrod"><img src="store/image/data/1rrod.gif" width="92" height="92" /></a>
   <?php } if (isset($_GET['step']) == 3) { ?>
   END
   <?php } else {?>
   Please select which type of Xbox 360 you have<br />
    <a href="registration.php?step=2&console=xbox"><img src="images/xbox360.gif"></a>
    <a href="registration.php?step=2&console=xboxslim"><img src="images/xbox360e.gif"></a>   
    <?php } ?>
So, first step (which is bottom), lets you select which type of console it is - only two possible choices.  That then passes that data to step 2, which is what issue the console is having. 

Now I've tried this with $_POST, as I would prefer to work that way.  I've experimented with $_SESSION to try and pass everything I need, using code found elsewhere.  But I just can't get it to pass from page to page and finally be able to use it to email in the final step.

Final issue - I want to use images instead of buttons to be able to pass the variables.  I've found that using hidden type input does work but I think this issue is related to the above one.

Thanks!

Jason
