There are seats that need to be assigned to visitors, for each visitor I check if the seat is available, if it is, give the value 'x' for 1 $visitor until there are no visitors left. I want to execute a line of code for x times, x = the value of visitors. As the code is now, I want to suggest 2 visitors a seat by giving the value 'x'. I will use the values as follows: 1 = available 0 = is not available x = was available, and now it's a suggested seat The problem: I want to have a output of two X's, but as the script is now, it generates three X's, and I don't know why. The question: How do make my script so that it will output two X's (the value of $visitors)? The output: Visitors: 2 Array ( [0] => Array ( [seatAvailable] => 0 [seatNumber] => 1 ) [1] => Array ( [seatAvailable] => 0 [seatNumber] => 2 ) [2] => Array ( [seatAvailable] => x [seatNumber] => 3 ) [3] => Array ( [seatAvailable] => x [seatNumber] => 4 ) [4] => Array ( [seatAvailable] => x [seatNumber] => 5 ) ) My code <?php $visitors = 2; $seats = array( array( 'seatAvailable' => '0', 'seatNumber' => '1' ), array( 'seatAvailable' => '0', 'seatNumber' => '2' ), array( 'seatAvailable' => '1', 'seatNumber' => '3' ), array( 'seatAvailable' => '1', 'seatNumber' => '4' ), array( 'seatAvailable' => '1', 'seatNumber' => '5' ), ); echo "Visitors: ".$visitors; echo "<ol>"; foreach($seats as &$val){ //If not available if($val['seatAvailable'] == '0'){ //echo "<li>not available</li>"; } //If available elseif($val['seatAvailable'] == '1'){ //Give available spots the value X, for as many as there are $visitors for($i=0;$i<$visitors;$i++){ $val['seatAvailable'] = 'x'; } } } echo "</ol>"; echo "<pre>"; print_r($seats); echo "</pre>"; ?>

Whats up guys. I've created two links in an html document. The problem is the JavaScript below gives me a value of undefined after running the for loop. I know this has something to do with closures, which I don't have much experience with so I can't figure out why the value of links is undefined. JavaScript: window.onload = function getLinks(){ var links = document.links; for(var i = 0, count = links.length; i < count; i++){ links[i].onclick = function(){ alert(links[i].href); return false; }; } }; html: <body> <p><a href="linkOne.html" id="link" target="linkOne">Link B</a></p> <p><a href="linkTwo.html" id="link" target="linkTwo">Link A</a></p> <script src="js/handleLinks.js"></script> </body> </html>

Hi, It's my first time to used foreach loop to display data from database and also used foreach loop to display textboxes Now, I felt difficulties in saving data from the textboxes displayed by foreach. Here is my code: <html> <head> </head> <body> <form name="operator_report" action="" method="post" autocomplete="off"> <?php ob_start(); include "connection.php"; $save = isset($_POST['save']); //insert data to database if($save) { $compound_type = $_POST['compound_type']; $op_output = $_POST['output']; $c_output = $_POST['output']; $reject_type[] = $_POST['reject_type']; $reject[] = $_POST['reject']; for($s = 0; $s < count($compound_type) ; $s++) { //---save operators output to op_output, in this part i don't have problem in saving the data saved correctly if ($op_output[$s] !="") { $sql = "INSERT INTO op_output (op_number, process_id, shift_id, shift_date, shift_type, compound_type, compound_output) VALUES ('001', '4', '1','2013-07-16', '1', '$compound_type[$s]', '$op_output[$s]')"; $result = mysql_query($sql, $con); } //---this part I need help in saving reject. //---I guess i have the problem here in looping ... //---this code did not work.. for($i = 0; $i < count($reject_type[$s]) ; $i++) { if($reject[$i] != "") { $sql_re = "INSERT INTO op_reject (op_number, compound_type, reject_type, reject) VALUES ('001','$compound_type[$s]', '$reject_type[$i]', '$reject[$i]')"; $result_re = mysql_query($sql_re, $con); } } } } $id = 'Final Mix'; if($id == 'Final Mix') { echo "<fieldset>"; echo "<legend><H1> Operator's Output and Reject</H1></legend>"; echo "<table>"; echo "<tr>"; echo "<th>Compound</th>"; echo "<th>Output</th>"; //query to select reject acronym $sql = "select r.reject_acro, r.reject_id from process_list AS p LEFT JOIN reject_list AS r ON p.reject_id = r.reject_process_id where p.process_name LIKE '" .$id. "%'"; $rsd = mysql_query($sql); while($rs = mysql_fetch_assoc($rsd)) { $reject[] = $rs['reject_acro']; $reject_id[] = $rs['reject_id']; } if(empty($reject)) { echo""; } else { //display reject acronym as header foreach ($reject as $reject) { echo "<th style='border:none;'><input type='text' name='reject_type[]' id='reject_type' value='$reject' style='border:none; font-weight: bold; ' size='5'></th>"; } echo "</tr>"; } //query select compound_type $sql_comp = "SELECT compound_id, compound_type FROM compound_list ORDER BY compound_type ASC"; $res = mysql_query($sql_comp); echo "<tr>"; while($comp = mysql_fetch_assoc($res)){ $compound_type = $comp['compound_type']; //---display compound_type echo "<td style='border:none;'><input type='text' name='compound_type[]' id='compound_type' value='$compound_type' style='border:none;' size='10'readonly='readonly'></td>"; //---input box for output echo "<td style='border:none;'><input type='text' name='output[]' id='output' value='' size='7'></td>"; //----i used foreach to loop textbox in every reject acronym. foreach($reject_id AS $reject) { echo "<td style='border:none;'><input type='text' name='reject[]' id='reject' value='' size='7'></td>"; } echo "</tr>"; } echo "</table>"; echo "</fieldset>"; } ?> <input type="submit" name="save" id="save" value="Save"> </form> </body> </html> I also attached my sample output screenshots and the database. Here is the sample scenario. Compound Type---Output---SC---SP---SH--- P28--------------10-------------1-----2 P32--------------20--------5--------------- P32NW--------------------------3---------- I need to save data on op_reject like this: op_number---compound_type----reject_type---reject 001----------P28---------------SP------------1 001----------P28---------------SH------------2 001----------P32---------------SC------------5 001----------P32NW------------SP------------3 Sad to say in my code in saving using forloop it did not work. I post it because i am hoping somebody can help me, but I also tried my best to fixed this. Any help is highly appreciated. Thank you so much. sample.zip -

I've been given a function that return all the list of data in an array. Only that function I can update nothing else specially on the database. From all the list of data, by using foreach I can print all the list of data. But my problem now is on the list of data e.g. (name, address, phone_number, zip_code). . How can I make a condition that will only show all the data by the same zip_code or name whatever. e.g. (John, John, John, John) for me it will be easy if i have access on the database, but unfortunately I don't have. Anyone can help me with this?
