PHP - Resetting A Form?

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]

Hello,

I'm working on a dynamic text form (I guess thats what its called). Basically, I have a html page that echos in some PHP code. What the PHP code does is show different strings of text depending on a variable:

Code: [Select]
<PHP?
$brief1_info = "brief info goes here";
$brief1 = 0;

if (isset($_POST['brief1Go'])) {
$brief1 = $brief1 + 1;
}
else if (isset($_POST['brief1Back'])) {
$brief1 = $brief1 - 1;
}


$breif1Controller = "
<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">
<input type=\"submit\" name=\"brief1Back\" id=\"brief1Back\" value=\"BACK\" />
</form>

<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">
<input type=\"submit\" name=\"brief1Go\" id=\"brief1Go\" value=\"CONTINUE\" />
</form>";



if($brief1 == 0){
$brief1_info = "<b>Welcome Commander,</b> you are currently viewing the Mission Control Brief page, here you can view all your missions that you need to complete in order to advance through your prestiges. You will need to follow your briefs carefully in order to succeed. <br /><br />

";
}
else if($brief1 == 1){
$brief1_info = "Okay, let me show you around the place ...";
}
else if($brief1 == 2){
$brief1_info = "brief is on 2";
}


?>
The problem is, the BACK and CONTINUE buttons don't work. If $brief1 equals 0, and the user presses continue, the is should go to 1, and the brief1_info string is changed (so some different text shows in my html). It actually works when brief1 is on '0', but when its on 1 and the user pressed continue, the brief1 is changed to 1, but because the submit button refreshes the page, the variable is re-read again, and thus is reset back to 0.

Is there a way around this? Or is there a better method than what I'm doing?

Thanks

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]
<?php

session_start();
 // include("connect1.php");
 //include('bouncer_final.php');
// include('frames/encounters.php');
 require_once("shoutbox/dbconnect.php");

Hi, I think this is probably a logical error rather than a syntax one

I have a function that displays the first image in a photo album in large and all the photos in it as thumbnails. I have a next and previous button that allows you to scroll through them (in large) and by clicking a specific thumbnail you can load that picture in large. My problem is that the pictures are stored in an array and the one to be shown large is selected by $keyid.

My problem is that selecting a thumbnail resets the $keyid so that clicking next doesn't load the next image but the second. i.e. if you press the next arrow then click the 4th thumbnail and then click the next arrow again it loads the 2nd picture rather than the 5th as it should.

How can I avoid this happening?

This is my code:

generateThumbnails();

$act = 0;

$keyid = (isset($_GET['keyid']) ? $_GET['keyid']:'0');

$Picturecount = (count(glob("" . $dir . "*.jpg")))/2;

$thumb_selected = (isset($_GET['thumb']) ? $_GET['thumb']:'');

$picture_array = glob("$dir*");

if ($thumb_selected !==""){
$dirName  = substr($thumb_selected,0,strpos($thumb_selected,basename($thumb_selected)));
$thumbName = basename($thumb_selected);
$thumbFile = $dirName.$thumbName;
$selected = str_replace('_th.jpg','.jpg',$thumbFile);
foreach ($picture_array as $search){
$keyid = array_search($selected,$picture_array);
$large = $picture_array[$keyid];
}}

else{
if($keyid > (2*$Picturecount-1)){
$keyid = ($keyid - (2*$Picturecount));}
if($keyid < 0){
$keyid = (2*$Picturecount+$keyid);}
$large = $picture_array[$keyid];}

echo "

<tr><td><a href='?album=$album&amp;keyid=" . ($_GET['keyid']-2) . "'>Previous</a></td><td></td><td align='right'><a href='?album=$album&amp;keyid=" . ($_GET['keyid']+2) . "'>Next</a></td></tr>

<tr><td colspan='3' height='300' width='400' align='center'><img src='$large' alt=''></td></tr><tr><td height='50'></td></tr>";



Any help would be massively appreciated. Thanks very much!

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!
