PHP: Email All Form Values

cornerblue (CornerBLUE, Inc.) — Thu, 19 Jul 2007 23:09:40 GMT

If you need a very basic contact form and don't want to write extra code for putting the value of each field into the email, you can use this basic email. It works best if you name your form fields something legible, such as First_Name



if (isset($_POST['Submit'])) {

	// Prepare message

	$msg = "Time: " . date("m/d/y g:ia", time()) . "\n";

	foreach ($_POST as $field=>$value) {

		if ($field != "submit") $msg .= $field . ": " . $value . "\n";

	}

	

	if (mail("TOEMAIL", "SUBJECT", $msg, "From: FROM_NAME ")) {

		// Email was sent

	} else {

		// Erro sending email

	}

}

PHP: Pass On Values For A Multi-Page Form

cornerblue (CornerBLUE, Inc.) — Thu, 19 Jul 2007 23:03:48 GMT

While the best way to do this involves saving the data into a database and passing an encrypted reference to the next page, this method will suffice for non-critical uses.



foreach ($_POST as $field=>$value) {

	echo "";

}

CSV Parser / Writer for PHP

CSV Parser / Writer

Example A:



//cell separator, row separator, value enclosure

$csv = new CSV(';', "\r\n", '"');



//parse the string content

$csv->setContent(file_get_contents('data.csv'));



//returns an array with the CSV data

print_r($csv->getArray());

Exemple B:



$csv = new CSV(';', "\r\n", '"');

//sets up the content through an array

$csv->setArray(

	array(

		array('col"una1', "colu\r\nna2"),

		array('col;una3', 'coluna4')

	)

);

//retorns string with the CSV representation

print $csv->getContent();

	var $cellDelimiter;

	var $valueEnclosure;

	var $rowDelimiter;



	function CSV($cellDelimiter, $rowDelimiter, $valueEnclosure){

		$this->valueEnclosure = $valueEnclosure;

		$this->rowDelimiter = $rowDelimiter;

		$this->o = array();

	}

	function getArray(){

		return $this->o;

	}

	function setArray($o){

		$this->o = $o;

	}

	function getContent(){

		if(!(($bl = strlen($b = $this->rowDelimiter)) && ($dl = strlen($d = $this->cellDelimiter)) && ($ql = strlen($q = $this->valueEnclosure))))

				$i += $ql - 1;

			elseif(!$e && substr($s, $i, $dl) == $d){

				$o[$r][++$c] = '';

				$i += $dl - 1;

			}

			else

				$o[$r][$c] .= $s[$i];

swap values without temporary variable

nevadalife (nevada) — Sat, 23 Sep 2006 17:40:36 GMT

The XOR swap algorithm is an inefficient method of swapping two variables. http://en.wikipedia.org/wiki/Xor_swap_algorithm



void XORSwap(void *x, void *y)

{

   *x ^= *y;

   *y ^= *x;

   *x ^= *y;

}
