PHP, Form, and Textbox

ccirish · September 9, 2012

I'm trying to create a PHP Script that looks in a file for information, displays that information, and then the user can change the information in the fields if they so wish.

It pulls data just fine, but I cannot for the life of me get it to pull data from the text boxes and put it into variables. I've searched high and low and can't figure out what I am doing wrong.

Thanks for your help.

-bash-4.1$ vim feedmaker.php
<?php
if (!isset($_GET['id']) or !isset($_GET['game'])) die;
$feedid = $_GET['id'];
$roTa = $_GET['game'];
$file = "$feedid.feed";

$filex = fopen($file, "r");
$i = 0;
while (!feof($filex)) {
$line_of_text .= fgets($filex);
}
$members = explode("\n", $line_of_text);
fclose($filex);

$count = count($members);
$j = 0;
for ($j==0; $j<=$count; $j++){
  list($roTb, $aPT, $hPT, $aPTm, $hPTm, $tot, $om, $um, $aML, $hML) = explode("|",$members[$j]);
  if ($roTa == $roTb){break;}
}

function edit_line($members, $feedid){
list($roTb, $aPT, $hPT, $aPTm, $hPTm, $tot, $om, $um, $aML, $hML) = explode("|",$members);

$hPTn = $_POST['hPTc'];
$aPTn = $_POST['aPTc'];
$totn = $_POST['totc'];

echo "<html>\n";
echo "<head>\n";
echo "</head>\n";
echo "<body>\n";
echo "<table border=\"0\" cellpadding=\"1\" cellspacing=\"1\" style=\"width: 250px; \">\n";
echo "<caption>\n";

if (isset($_GET['edit'])) edit_line($members[$j],$feedid);

Ok, looking at your script, decided to make some improvements to it. You can choose to use it or not, I just find this a bit more manageable and less error proned.

As to your issue I am not sure what you are getting at in "putting into variables" . So when as user submits the form, you want to check for that and put the POST data into a variable? Or do you want it to write it back to the file? If you can clarify that a little bit, I will be more than happy to assist.

<?php
if (!isset($_GET['id']) or !isset($_GET['game'])) die;
$feedid = $_GET['id'];
$roTa = $_GET['game'];
$file = "$feedid.feed";

$members = file($file);
$count = count($members);

for ($j=0; $j<=$count; $j++){
  list($roTb, $aPT, $hPT, $aPTm, $hPTm, $tot, $om, $um, $aML, $hML) = explode("|",$members[$j]);
  if ($roTa == $roTb){break;}
}

function edit_line($members, $feedid) {
list($roTb, $aPT, $hPT, $aPTm, $hPTm, $tot, $om, $um, $aML, $hML) = explode("|",$members);

$hPTn = isset($_POST['hPTc'])?$_POST['hPTc']:'';
$aPTn = isset($_POST['aPTc'])?$_POST['aPTc']:'';
$totn = isset($_POST['totc'])?$_POST['totc']:'';

$display = <<<DISPLAY
<html>
<head>
</head>
<body>
<table border="0" cellpadding="1" cellspacing="1" style="width: 250px; ">
<caption>
Game Data:</caption>
<form method="post" action="feedmaker.php?update&id={$feedid}&game={$roTb}&aPT={$aPTn}&hPT={$hPTn}&tot={$totn}">";

    echo $display;
}

if (isset($_GET['edit'])) edit_line($members[$j],$feedid);
