PHP - How To Stop Array Id As Variable Resetting

That's really the only way i can categorize this particular question.

I have a site loading a form into an iframe. probably not the smartest thing to do but I've built a one-page portfolio site that scrolls to each anchor point with the scrollTo script.  None the less, my form loads into my frame.

I started thinking about usability and how odd it might be to a non-techie, non-webby visitor to go to the form, submit and then maybe want to send another message. Although not very probable, it's the stuff we don't anticipate happening that usually gets us in deep.  Really, what I'm looking for is something where after the visitor submits the form and it says "thank you for sending us an email" that it would either automatically reset my index page OR give the visitor the option of manually resetting the page.

my form

Code: [Select]
<form method="POST" action="mailer.php"><br />
Name:<br />

   <input type="text" name="name" size="50"><br>
   <br />
   E-Mail:<br>
   <input type="text" name="email" size="50"><br>
   <br />
   Comments:<br>
   <textarea wrap="soft" rows="5" name="message" cols="48"></textarea>
   <br>
   <br>
   <input type="submit" value="Submit" name="submit">
</form>


php script
Code: [Select]
<?php
if(isset($_POST['submit']) || isset( $_POST['submit_x'] )) {

$to = "email@mydomain.com";
$subject = "Contact from a visitor";
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
 
$body = "From: $name\n E-Mail: $email\n Message:\n $message";
   
echo "Your email has been sent to $to!";
mail($to, $subject, $body);

} else {

echo "blarg!!!";

}
?>

I'm having trouble with some foreach statements.  I'm pretty sure I've narrowed it down to one foreach statement.  Not sure where to go from here. 
Code: [Select]
// output column headers
$rows=1;
$cols=0;
foreach ($colarr as $col){
//echo "<pre>"; print_r($col); echo "</pre>";
$text=str_replace("<br>", "\r\n", $col['desc']);
$objPHPExcel->getActiveSheet()->SetCellValue($xlcols[$cols].$rows, $text);
$objPHPExcel->getActiveSheet()->getStyle($xlcols[$cols].$rows)->getAlignment()->setWrapText(true);
$objPHPExcel->getActiveSheet()->getStyle($xlcols[$cols].$rows)->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
$cols++;
}
$rows++;

// output data rows
if (isset($apptable['retarr']) && isset($apptable['retarr']['rs']) && count($apptable['retarr']['rs'])>0){
foreach ($apptable['retarr']['rs'] as $row=>$r){
if (is_numeric($row)){
//echo '<pre>'.print_r($apptable).'</pre>';//exit;
$cols=0;
foreach ($r as $col=>$c){
if (isset($colarr[$col])){
//echo '<pre>'.print_r($colarr[$col]).'</pre>';//exit;
//echo "this is xlcols: ".$xlcols[$cols].$rows; echo " ";
//echo "This is col: ".$col; echo " ";
//echo "This is r[col]: ".$r[$col]; echo "<br>";
$objPHPExcel->getActiveSheet()->SetCellValue($xlcols[$cols].$rows, $r[$col]);
$objPHPExcel->getActiveSheet()->getStyle($xlcols[$cols].$rows, $r[$col])->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
$cols++;
}
}
$rows++;
}
}
}

The first section (output column headers) prints column names to an excel spreadsheet.  The next part (output data rows) puts the data in an excel spreadsheet.  The problem I have is that the data rows don't match the header columns.  I think this is because the array $colarr is not after the first foreach loop.  I've tried to

reset, asort, and sort to move it back to the beginning, but none of those worked.  And this  $reset_array_keys = array_values($numerically_indexed_array);
Any suggestions on what I should do? 

Output of print_r($colarr[$col]).
Code: [Select]

Hi, I have a battle script that has a monster and player fighting. The hit points keep resetting on both characters. I set my session variables in intro.php, and included a session_start(); on the pages leading up to my main battle page. I set the array names of both $monster stats and $player stats to $_SESSION variables and initialized them on a separate page before the main page. My monster and players hitpoints keep resetting so no one dies. Any help GREATLY appreciated. Thanks. Derek

here is the intro page where I initialize the stat session variables.

Code: [Select]
<?php
 //include("connect1.php");
session_start();
// include('bouncer_final.php');
 
 //include("bouncer.php"); // kicks the person off if session is not set, its the bouncer, big and fat man.
 
$_SESSION['charname']='';
$_SESSION['player']['stats']['playerHP'] = 100;
$_SESSION['player']['stats']['playerMana'] = 100;
$_SESSION['player']['stats']['playerDmgLow'] = 1;
$_SESSION['player']['stats']['playerDmgHigh'] = 10;
$_SESSION['player']['stats']['playerHitRollLow'] = 1;
$_SESSION['player']['stats']['playerHitRollHigh'] = 20;
$_SESSION['player']['stats']['playerDefense'] = 5;
$_SESSION['player']['stats']['Teardrop_Ocean_Protectors'] = 3;
 
$_SESSION['monsters']['Ocean']['octalisk']['exp']=10;
$_SESSION['monsters']['Ocean']['octalisk']['mana']=100;
$_SESSION['monsters']['Ocean']['octalisk']['hp']=100;


/* End */

here is the main battle page where all my battle coding goes on, and I declare the session variables equal to my array names near the top .

Code: [Select]
$word = 'numbers';
$numbers= array('1', '2', '3', '4');

echo $$word[0];
I expected the output to be '1'. It ended up being nothing... 

Why does this not work? Is it not possible to have a variable variable array? And if not, is there a workaround?

Cheers,

Hi,

I want to create a forgotten password page, where the user enters in their email address, the script queries the database for that email address, creates a unique ID, stores that unique ID in the database, then emails the unique ID and the User ID off to the user in an HTML link e.g. http://somesite.com/reset-password.php?userId=2&uniqueId=132832189312978312. The reset page would then match the unique ID to the one in the database and let them enter in a new password into the form.

Ok so I can do most of that so far except from the emailing to the user. I'm running an Ubuntu Server 10 at the moment as my test server which is on my local network. Do I need to set up a mail server on that for php mailing to work, or can I use some external SMTP for sending? I've had a play round with the PHP mail() function but it won't send anything at the moment. I'll also need some code for when the site is running in the hosted live environment as it will likely use their mail servers.

What's the best way to go about doing this?
Many thanks!

Hello Guys.

I have a question here..

I have a photo upload script that uploads photos to the server and then sends the photo name to another page via POST.

I only have one var name called $image_all

when I echo it this is what I get (When uploading 2 files)
Code: [Select]
This is the list 2011-12-05_0751.png,2011-12-05_0747.png

I also tested with "explode"
Code: [Select]
print_r(explode(',', $image_all, 10));
 and I get this

Code: [Select]
Array ( [0] => 2011-12-05_0751.png [1] => 2011-12-05_0747.png [2] =>
What I would like for it to do is assign an incremental var name to each image uploaded and passed in the POST.

Like this

$image1 =  2011-xx.png
$image2 = 2011-xx.png
$image3 = 2011-xx.png

It should created the variable names dynamically based on the number of images (Up to 10)

Thanks for your help!

Hi Everyone   Please checkout the below code:   foreach ($joiners as $joiner) { $town = explode(',', $joiner['address']); if (isset($town[2])) { $town = $town[2]; $get_available_towns[] = $town; $get_available_towns = array(); }

 foreach ($joiners as $joiner) {

                $town = explode(',', $joiner['address']);

                if (isset($town[2])) {
                    $town = $town[2];
                    $get_available_towns[] = $town;

                    $get_available_towns = array();




                }

I don't really understand what is happening. I know the code and everything is correct and it works but I really don't understand how the loop, arrray and variable is working. I wanted to print_r the $get_available_towns outside the loop but it would not work without the square brackets but also I did not even know the square brackets were required. The point was to loop through the data and print all the values. I understand how loops, array's and variables work but I've not seen them used like this. This makes me think I am missing some basic knowledge but I have looked around and I can't see any examples of how loops and arrays are used like this. I have also checked the php manual but still no joy. Can you guys tell me where I could find the information that would have examples on how something like the above code would work?

Hey, im struggeling with a small piece of code....

Thats my code:

Global $user_ID;
$user_ID = get_current_user_id();

   echo"User number $user_ID is loggedin";

Echo gives me this:
"User number 2 is loggedin"

 

Now i want to add it to my array:
 

$atts['href'] .=  $user_ID . 'abc';

'href' is set to "https://test.com/"

What im getting now ist

https://test.com/abc

 

Can someone tell my why the '2' is missing??

 

 

Hi,

I need help with this, I am quite new to arrays. This one works fine:

echo array_sum(array(34,19,22,17,7,22,8,23,17,31,21,32,7,29,13,7))/count(array(34,19,22,17,7,22,8,23,17,31,21,32,7,29,13,7));
which gives "19..."

it gets average number. What I want to put the values in the array in a variable so I do this:

$t = "34,19,22,17,7,22,8,23,17,31,21,32,7,29,13,7";

so why can't I use array like this:

echo array_sum(array($t))/count(array($t));

I need to use variable in array, please someone help.

Hello. Can someone show the syntax to echo the variable from the array below that is showing "2010-08-31 23:19"? I need to grab that date and use it elsewhere in my script. Thanks.

Code: [Select]

array(19) {
  ["name"]=>
  string(8) "com_jumi"
  ["params"]=>
  array(0) {
  }
  ["mainframe"]=>
  &object(JSite)#2 (6) {
    ["_clientId"]=>
    int(0)
    ["_messageQueue"]=>
    array(0) {
    }
    ["_name"]=>
    string(4) "site"
    ["scope"]=>
    string(8) "com_jumi"
    ["_errors"]=>
    array(0) {
    }
    ["requestTime"]=>
    string(16) "2010-08-31 23:19"
  }

Is this right? 


$admin = array('24.68.200.235','24.68.214.97');
$visitor_ip = $_SERVER['REMOTE_ADDR'];
if($visitor_ip == $admin) {

Hi,

I am basically trying to apply a different amount to $defineMe for certain numbers of an array .. in this case it's array numbers 11 - 16

Code: [Select]
<?php
 
if ($defineNumber > 11 and $defineNumber < 16) {
$defineMe = 35.00;
} else {
$defineMe = 50.00;
}

$defineNumber[01] = array('name'=>'Product 1');
$defineNumber[02] = array('name'=>'Product 2');
$defineNumber[03] = array('name'=>'Product 3');
$defineNumber[04] = array('name'=>'Product 4');
$defineNumber[05] = array('name'=>'Product 5');
$defineNumber[06] = array('name'=>'Product 6');

$defineNumber[11] = array('name'=>'Product 11');
$defineNumber[12] = array('name'=>'Product 12');
$defineNumber[13] = array('name'=>'Product 13');
$defineNumber[14] = array('name'=>'Product 14');
$defineNumber[15] = array('name'=>'Product 15');
$defineNumber[16] = array('name'=>'Product 16');
  
?>

hello all,

I have an array value in my post array ($_POST['check0'] ) that I am trying to break up into php variables. For some reason if I do this:
$var1 = $_POST['check0'][0];
all I get is the first letter of the string from the first value of the array?

Hi everybody, im reading up on arrays and im still stuck...

Is it possible to assign an array to a variable? I need something like...

Code: [Select]
&needvariable = $row->User
Hopefully this makes sense...

I am trying to use the variable $RATETHESE to include an array into file A. The array is in file B.

PhP File A
include_once(dirname(__FILE__) . '/PhpFileB.php');
global $RATETHESE;
$VALID_RATING_IDS = $RATETHESE;


Php File B
$RATETHESE = "array("1", "2");"


For some reason it is printing the array on the page, and the array is not being used to run the script. Did i do anything wrong?
