Newb here trying to build a form that works with ints to count how many red shirts die in a classic episode of star trek (exercise to get better with forms and ints). I have an error which reads as '7 Error message: Undefined index: rsTot'. I have tried a few things and read that setting it(casting it?) as a float was the safest way to work with the int, however each thing i've attempted results in some sort of error so after a day of reading and trying i'm very confused and hoping for an answer I can understand here. I have read through stackOverflow for an answer but not seen one which i can understand and apply that speaks to the problem i'm having of initially entering and process a number as an int which i can later do some math on. error can be seen here: http://zephir.seattlecentral.edu/~jstein11/itc250/z14/w03c0102_OOPform/w03c0102_OOPform.php <?php //w03c0102_OOPform require '../inc_0700/config_inc.php'; #provides configuration, pathing, error handling, db credentials //END CONFIG AREA ---------------------------------------------------------- $rsTot = (float)$_POST['rsTot'];// float more forgiving int $rsSurvived = (float)$_POST['rsSurvived']; $rsSum = $rsTot - $rsSurvived; $rsRatio = 0; # Read the value of 'action' whether it is passed via $_POST or $_GET with $_REQUEST if(isset($_REQUEST['act'])){$myAction = (trim($_REQUEST['act']));}else{$myAction = "";} switch ($myAction) {//check 'act' for type of process case "display": # 2)Display user's name! showName(); break; default: # 1)Ask user to enter their name showForm(); } function showForm() {# shows form so user can enter their name.

Hi I appreciate your help, the code is kinda simple actually but I'm having trouble The following code echo's the WRONG result a5611bcd::0::0::abccef01 I need this following result a5611bcd::fffafaff::fefffeef::abccef01 I suspect the issue is that those two middle values are too large for integer, I know about bcmath, but whats the best way to get correct results into INTEGER form.. must be integer form, basically I my variables below are closely named sorry about this... <?php $KEY = array(0xA5611BCD,0xFFFAFAFF,0xFEFFFEEF,0xABCCEF01); /*this is the model of how everything below should end up in $SKEY $KEY = array(0xA5611BCD,0xFFFAFAFF,0xFEFFFEEF,0xABCCEF01); */ //so I begin with this string $getSKEY and try to make it into the above model $getSKEY = "A5611BCDFFFAFAFFFEFFFEEFABCCEF01"; $SKEY = array( hexdec(substr($getSKEY,0,), hexdec(substr($getSKEY,8,16)), hexdec(substr($getSKEY,16,24)), hexdec(substr($getSKEY,24,32)) ); echo dechex($SKEY[0])."::". dechex($SKEY[1])."::". dechex($SKEY[2])."::". dechex($SKEY[3]) ; ?>

I have a php script that looks at a supplier website and queries from a pricing calculator, the script displays the result in a table. The result is my actual cost from my supplier and the price is displayed as a string. I need to convert my wholesale cost from a string to a value and then add my retail markup cost then display the Retail Cost as a string in my table. Unfortunately, I am a complete newbie and have been searching various methods, but no matter what I try, it fails. Here is the script: <?php // Request parameters $materialid = $_GET['materialid']; $sizeid = $_GET['sizeid']; $quantity = $_GET['quantity']; $numcolors = $_GET['numcolors']; // form URL for request //$url = "http://www.suppliersite.com/pricing?materialid=104&sizeid=37&quantity=1&numcolors=1"; $url = "http://www.suppliersite.com/pricing?materialid=".$materialid."&sizeid=".$sizeid."&quantity=".$quantity."&numcolors=".$numcolors; // Create DOM from URL or file $html = file_get_html($url); // Echo page //echo $html->plaintext; $price_per_item = $html->find('#price-per-item'); $total_price = $html->find('#total-price'); $description = $html->find('.description'); $name = $html->find('h3'); //echo $price_per_item[0]."<br />"; //echo $total_price[0]."<br />"; //echo $description[0]."<br />"; //echo $name[1]."<br />"; // Iterate through all combinations: echo "<table id=\"products\">"; echo "<tr>"; //echo "<th>Price per item</th><th>Total Price</th><th>Product</th><th>Description</th><th>Size</th><th>Quantity</th>"; echo "<th width=\"25%\">Price per item</th><th width=\"15%\">Total Price</th><th width=\"30%\">Product</th><th width=\"10%\">Size</th><th width=\"10%\">Colors</th>"; echo "<tr>"; $price_per_item = $html->find('#price-per-item'); $total_price = $html->find('#total-price'); $description = $html->find('.description'); $size = $html->find('select[id='.'top-sizes-select'.'] option[value='.$sizeid.']'); echo"<tr>"; echo "<td>".$price_per_item[0]."</td>". "<td>".$total_price[0]."</td>". "<td>".$name[1]->innertext."</td>". // "<td>".$description[0]."</td>". "<td>".$size[0]->innertext."</td>". "<td>".$numcolors."</td>"; echo "</table>"; echo "<br />"; echo "<div style=\"width:40%\">"; echo $description[0]; echo "</div>"; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-GB"> <head> <title>Extractor</title> <style media="screen" type="text/css"> #products { font-family:Arial, Helvetica, sans-serif; width:60%; border-collapse:collapse; font-size:12px; } #products td, #products th { font-size:1em; border:1px solid #777777; padding:3px 7px 2px 7px; } #products th { font-size:1.1em; text-align:left; padding-top:5px; padding-bottom:4px; background-color:#777777; color:#ffffff; } </style> </head> <body> </body> </html> Attached is a screenprint of the results, you will see the cost per item is $11.55 and I simply want to add 20% or as in the code: = price-per-item*1.2 -----so the price should show $13.86 per item I have tried to define a value such as: $RETAIL_price_per_item = $html->find(int('#price-per-item')*1.2); but that does not work I have tried many other versions and in different areas of the code but nothing works. Any help would be greatly appreciated. Thanks
