[Html form data parsing]

Missing php closing tag on the bottom: ?>

[Using commas in textbox and submitting data?]

You should probably also convert periods (.) and dont rely on everyone using commas

In addition i would remove whitespace etc.

$text = trim(str_replace(array(",","."), "", $text));

[Help Needed!]

The variables from POST does not match the one used in email body,

example: $apt1Field is declared from POST apt1 while inside email body it looks for variable $apt1

/* Information Variables */
$monthField = $_POST['month'];
    $apt1Field = $_POST['apt1'];
    $apt2Field = $_POST['apt2'];
    $apt3Field = $_POST['apt3'];
    $apt4Field = $_POST['apt4'];
    $apt5Field = $_POST['apt5'];
    $apt6Field = $_POST['apt6'];
    $totalField = $_POST['total'];
    $fromField = $_POST['from'];
    
    $body = <<<EOD
<br /><hr /><br />
Email: $month <br />
708 Front St: $apt1 <br />
708 1/2 Front St: $apt2 <br />
218 N. Park Ave: $apt3 <br />
220 N. Park Ave: $apt4 <br />
1236 Sycamore St: $apt5 <br />
1236 1/2 Sycamore St: $apt6 <br />
Total: $total <br />
From: $from <br />
EOD;

[A simple idea that needs a script]

I would go for an AJAX aproach, adding picked boxes in a db by a php backend file - if done with pure php you must have each click reloading the page adding up the picked boxes in a session array or to db.

Another variant is ofcourse to use javascript adding picked boxes either to a cookie or collecting all div id's in a hidden textfield that is treated by php on submitting the result page.

 

im sure there are many ways of doing it, i would go for the AJAX method.

[Load multiple images randomly from a directory]

Play around with these examples

$random1 = RandomFile("random");

$random1 = RandomFile("dir/myfolder");

$random1 = RandomFile("../path/to/myfolder");

[problems optimizing images]

I suspect you might be looking for something like this (simplified example)

<?php

// img_src.php

$id = $_GET['id']; // make GET id db safe

// query db for filename, content type and path based on requested photo id

header('Content-Type: image/jpeg');
echo file_get_contents('path/to/file/filename.jpg')

?>

 

Then call img_get.php for each photo like this to display it

<img src="img_src.php?id=foo" />

[Help Needed!]

It was an error on ending the heredoc syntax, but moving ; one line below is not the problem - adding space like this fixed it (showing from line 103)

  </tr>
</table>
</body>
</html>

EOD;

echo $theResults;

 

When that is said you dont need to run all this html through heredoc since you arent filling in any php variables at all as far as i can see

 

*edit* EOD without space in front of it, shows poorly in the code block on this forum

Also i recoment creating a better description rather than "Help Needed" etc when creating forum topics - most topics are created because the topic starter needs help.

[Fields array]

<?php

$fields = array(
'First_Name' => 'First Name',
'Last_Name' => 'Last Name',
'Card' => 'Card Number',
'Old_Card' => 'Old Card Number'
// and so on
);

$body = "We have received the following information from $_SESSION[username]:\n\n"; 
foreach($_REQUEST as $a => $b){
if(array_key_exists($a, $fields) && !empty($b)){
   $part1 .= sprintf("%20s: %s\n", $fields[$a], $b);
}
}

?>

[how to refer to the beginning of text string?]

<?php

$data = "ABCDEF";

if(substr($data,0,3) == "ABC")

?>

[Read remote file]

look at http://www.php.net/manual/en/function.file-get-contents.php

But if the server where the file is does not respond you cannot read it

[While and For loops]

You need a total results to do this easily, example

<?php

$i = 1;
while ($i <= 10) {
  $i++;
  
  if($i <> 10) echo "<hr>";
}

?>

[Form validation]

It is no problem to show the form again after it is submitted if an error exists, post form to the same file as you have the form and fill the form with the posted variables.

 

Example:

<?php

$complete = false;
$empty_arr = array();

foreach($_POST as $fieldname => $fieldvalue)
{
  if(empty($fieldvalue))
  {
    $empty_arr[] = $fieldname." was left empty";
  }
  ${$fieldname} = $_POST[$fieldname];
}

if(!empty($empty_arr))
{
  echo "<ul><li>";
  echo implode($empty_arr, '</li><li>');
  echo "</li><ul>";
}
else
{
  // no empty fields, prosess posted values already defined as $fielnames
  $complete = true;
}

if($complete == false)
{
echo <<<_HTML

<form method="post" action="{$_SERVER['PHP_SELF']}">
<p>Name:<br /><input type="text" name="name" value="$name" /></p>
<p>Email:<br /><input type="text" name="email" value="$email" /></p>
<p><input type="submit" name="submit" value="Send" /></p>
</form>

_HTML;
}

?>

 

When you mention instant red border on error fields that is mainly pure javascript validation, one example is http://www.formassembly.com/wForms/

[!isset vs empty]

$_GET, $_POST and $_REQUEST are all predefined variables, and returns empty if not set - and empty array "array()" is considered valid empty using empty()

[!isset vs empty]

I prefer to expect variable either as POST or GET and try to avoid the possibility for both, if you however expect both you could use REQUEST

<?php

if(empty($_REQUEST['var']))

?>

as empty returns false also if 'var' is not set, so it checks both if it is set and that its not empty

[Form validation]

I would never rely on javascript alone as this is easily manipulated if someone want to do so, you should always validate with php.  AJAX is my preferred method if validating along the form since i can ask the same php functions both times.

[Form validation]

You can start with this

<?php

function Check($data){
  // this example allowing: A to Z a to z 0 to 9 . , space(s) - @ _
  if(preg_match("/^[-A-Za-z0-9.,\s@_]+$/", $data))
  return true;
  else
  return false;
}

if(!Check($_POST['text'])){
echo "Illegal input found";
}

?>

[Split concatenated string]

Work with something like this

<?php

$input = "a:10 b:20 c:30 a:50 b:60 c:70 a:150 b:160 c:170";

preg_match_all('/c:(\d+)/',$input,$out);

$out = array_reverse($out);

while(list($key, $val) = each($out[0])){
   ${$key} = $val;
}

?>

[Url $_GET]

Its better to use a switch statement tho

<?php

switch($_GET['page']){
case 'home':
// include or whatever on home
break;
case 'news':
// include or whatever on news
break;
default:
// include or whatever when $_GET['page'] doesnt match other case, or dont exist
}

?>

 

[Select high from array]

Not sure i fully understand what you are doing, but look at

<?php

$values = array("Double-Glazing" => 3, "test" => 1, "test2" => 1, "test5" => 7);

rsort($values);

echo $values[0]; // 7

?>

[Remove last word]

another variant

<?php

$test = 'this is a test string';

echo implode(" ", array_slice(str_word_count($test, 1), 0, -1));

// this is a test

?>

[why this code is not updating the field in the mysql]

Then you have no post data from your form - for some reason

[why this code is not updating the field in the mysql]

add this on top of your script to debug whats posted and whats not, replace with $_GET to debug get variables

echo "<pre>";
print_r($_POST);
echo "</pre>";

[why this code is not updating the field in the mysql]

if ($_POST["$submit"])

if ($_POST["submit"])

[How to browse to a file on the server and insert the value into an input field?]

You cannot open the standard browse window on a server location, you have to make your own file browse window.

Look into http://no.php.net/manual/en/function.readdir.php - there is som user examples you can start with. Then you will have to use javascript in one way or another (easiest) to move filenames between browse window and form.
