PHP - The Php Side

Hi guys,
I'm using this EOD thingi in order to print a table and get it PDF. I am using TCPDF and following their examples to get the PDF output.
I need to print a php variable's value within the EOD.
Can you please help me out.
Below is the piece of code I'm running.

Code: [Select]
$tbl = <<<EOD
<table cellspacing="0" cellpadding="1" border="1">
    <tr>
        <td rowspan="4"><img src="images/m24.jpg"></td>
        <td align="right" width="150">From the desk of</td>
        <td>: $contat</td>
    </tr>
    <tr>
        <td align="right">E-Mail</td>
<td>: $email</td>
    </tr>
    <tr>
       <td align="right">Telephone</td>
   <td>: $telephone</td>
    </tr>
      <tr>
       <td align="right">Mobile</td>
   <td>: $mobile</td>
    </tr>
</table>
EOD;

the $variables are simply ignored. or even if I echo, there is no PHP value.
Can you guys please shed some light on this issue.
Pretty pleeeaaassseee

I have a text box and a submit button. I want that when the submit button is pressed, the value on the text box will be checked if it matches the values that are on my server before proceeding, and if they don't match it should give an error report and stop.

All I can make myself is the text box and the submit button, I have tried for hours to find a way to do the rest, but all I can find on the internet are vague explanations and information that a novice like me cannot use. It would be a shame to let me web site that I have worked hard on to go to waste because I cannot do this myself 

Thank you in advance

Hello guys. I was thinking on posting this under the mysql thread. but i think this can be solved by php.. anyway, i want to dump mysql data on the client side whenever a user logs out. how can i do this? thanks in advance.

hello,

since php is run server side, can i launch a program (.exe) on the server from a link?

I'm trying to learn how to validate a form using the php server side method. Everything I search is very different and old. Anyone have knowledge of a good tutorial or source that I could use? None of my books have anything about it either!

Thanks!

I'm in the habit of verifying input client side. For example, there is a field to enter a number, and I ensure that it is within a particular range using Javascript.

My backend PHP code does not do such checking... Is this bad? Should I be doing checking using my backend code and send a response back to the client to display a message? Admittedly, I avoid it, since it's a little extra work -- well more extra than just javascripts, IF-THEN-ALERT type statement.

This part of the question is based off of php so I'll put it here of course.

The idea behind this is jquery/ajax is going to get passed an id (eventid) from a dropdown select box inside a form and it's going to run a query to find all the events in my database with that same id. After running the query it's going to list them out and find the highest number of another field (label) and its going to add one to its value and then what I would like for it to is send it back to the form in the jquery/ajax and and place that label inside of the existing input text field in the form.

So I'm asking is if my code is presented and is doing what I"m attempting it to do on the php side and if so if I can take out the print tag of the input text field.


$eventid = $_GET['eventid'];
$result = mysqli_query("SELECT * FROM `events` WHERE `event_id` = '$eventid'");
$list = mysqli_num_rows($result);
$label = $list + 1;
print '<input type="text" name="label" class="text" readonly="readonly" value="' . $list . '" />';

I am doing server side validations using php and jquery.Its validating properly.But problem is the erros messages are displaying on the top of the page.I want to display side of field.All of the validations store in array.How to display errors to side of the field.

So I have been working on a script on my local server. This script is a poll script and essentially people are voting either Republican or Democrat which is submitted with a myriad of other information into the database. The database has a single column for both the D and the R. I need to get a sum of both of those individually and display them onto a web page. Previously I had used the SQL below to achieve a dynamic database that updates with the votes and then displayed that on the page, however my host that I am going remote with, will not allow me to use it because I need root access.
Code: [Select]
CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost` SQL SECURITY DEFINER VIEW `totals` AS select count(`votes`.`Party`) AS `total`,`votes`.`Party` AS `party` from `votes` group by `votes`.`Party`;
Please advise how I can achieve what I need through PHP rather than the SQL way I was going before. Thanks!

I want to do simple client side validation but I don't know Javascript.  Can someone point me to an easy example on how to implement or post something here?

Hey guys just thought I'd introduce myself as it's a polite thing to do. My name is Nick I am currently a front end developer and love learning new technologies so it looks like PHP is my next step.   I hope to learn and give whatever knowledge I can back

Hello,   I want to grab some data using a script from this site. But I am stuck right at the beginning. If you make a selection with the drop down boxes you get some output. For example you select: Selecteer competitienaam:  Najaarscompetitie 2014
Selecteer competitiegroep:  Eredivisie dames
Selecteer weergave: Programma (incl. uitslagen en stand)
Optioneel poule filter:  De Treffers R
Selecteer poule(s): Eredivisie - Poule A   I want to grab this output. When I look at the page source it is inside an iframe:

<iframe src="http://www.nttb-competitie.nl/" width="100%" height="1200" scrolling="yes" frameborder="0" name="NTTB_Competitie"></iframe>

I figured out: The script on the site first it gets url:

http://www.nttb-competitie.nl/selectie.php?anr=0

And after last selection it gets url:

http://www.nttb-competitie.nl/web_programma.php?reset=0&pidString=1009267&sc=0&vastgesteldeAfdelingsnr=0&cnid=10085&cid=10704&view=programma&pf=1269&pid=1009267

My problem is when I copy those URL's in a webbroser I get a page with only the words:

Ongeldige aanroep!

Which means "Invalid Call!"   So my question is: How can I grab the data instead of this stupid message. Is it even possible or is it somehow protected?   Please help!    

Basically what I am trying to achieve is making sure any $page called originates from my server, but if no $page is defined, to include a default page I have set up. This is my code, and I cannot figure out what's wrong with it.

Code: [Select]
<?php
  $path = 'pages/';
  $extension = '.txt';
 
  if ( preg_match("#^[a-z0-9_]+$#i",$page) ){
    $filename = $path.$page.$extension;
    include($filename);
  }
if (!$page)
include 'pages/main.txt';
?>
An example URL I am using is www.mywebsite.com/index.php?$page=pages/tester
What am I doing wrong?

Hello.

I recently posted about getting my top nav to work which it does now (with thanks) but im having trouble getting my side navs to work. i have tried various things but i think its just a case of getting the where clause right.

see what you think. any help would be great

these are my files.

includes/navL1.php  - which does the top navigation
includes/navL2.php  - which does the left navigation main
includes/navL3.php  - which does the left navigation sub
admin/layouts/admin_topnav.php
admin/layouts/admin_leftnav.php
admin/layouts/index.php



ok so. admin topnav.php code looks like this and works

Code: [Select]
<?PHP
require_once("../includes/initialize.php");
global $topNav;
global $pageName;
?>
<div id="navWrapper">
<?PHP
$topNav = navL1::find_all();
?>
  <div id="ddtabs3" class="solidblockmenu">
<ul>
<?PHP foreach($topNav as $topNavs): ?>

<li><a <?PHP echo ($pageName == $topNavs->title ? 'class="selected"' : '')?> href="<?PHP echo $topNavs->title; ?>.php" id="<?PHP echo $topNavs->title; ?>"><?PHP echo $topNavs->title; ?></a></li>
<?PHP endforeach; ?>
</ul>
</div><!--  #ddtabs3-->
</div><!--  #navWrapper-->


now i need when a top nav is selected i need the correct left nav main and subs to show.

this is how my left nav looks at the moment

Code: [Select]
<?PHP
require_once("../includes/initialize.php");
global $topNav;
global $pageName;
?>

SOME ACCORDION SCRIPT GOES HERE

<div class="arrowlistmenu">
<?PHP
$nav1 = navL1::find_all();
$nav2 = navL2::find_by_nav();
$nav2 = navL2::find_by_nav();
?>
<?PHP foreach($nav2 as $nav2s): ?><h3 class="menuheader expandable">

// MAIN LEVEL

<li><a <?PHP echo ($pageName == $nav2s->title ? 'class="selected"' : '')?> href="<?PHP echo $nav2s->title; ?>.php" id="<?PHP echo $nav2s->title; ?>"><?PHP echo $nav2s->title; ?></a></li></h3>
<?PHP endforeach; ?>


// SUB LEVEL

<ul class="categoryitems">
<?PHP foreach($nav3 as $nav3s): ?>

<li><a <?PHP echo ($pageName == $nav3s->title ? 'class="selected"' : '')?> href="<?PHP echo $nav3s->title; ?>.php" id="<?PHP echo $nav3s->title; ?>"><?PHP echo $nav3s->title; ?></a></li>
<?PHP endforeach; ?>
</ul>

</div><!-- #End arrowlistmenu -->
<img src="images/wrapper/loading.gif" alt="loading..." id="Pageloading" height="28" width="28" style="visibility:hidden;float:left;" />



this is the code im trying to get to work in my includes files that i can seem to get my head around


includes/navL2.php
Code: [Select]
public static function find_by_nav(){
global $database;
global $topNav;
$sql = "SELECT * FROM ".self::$table_name." WHERE title="$topNav" LIMIT 1";
$result_array = self::find_by_sql($sql);
return !empty($result_array) ? array_shift($result_array) : false;
}

the find_by_sql($sql) looks like this but i dont think you need it
Code: [Select]

public static function find_by_sql($sql){
global $database;
$results_set = $database->query($sql);
$object_array = array();
while($row = $database->fetch_array($results_set)){
$object_array[] = self::instantiate($row);
}
return $object_array;
}


im trying to use the same code to pull the sub levels inside includes/navL3.php



if any of this makes sense please could you point out whats wrong
thanks
ricky
