  1. Hi everyone, I'm having troubles with query from database. I want to select all from one table and select sum from second table in the same time. Is this possible? Here is my script: $conn = mysqli_connect('localhost', 'root', '', 'test'); if (!mysqli_set_charset($conn, "utf8")) { printf("Error loading character set utf8: %s\n", mysqli_error($conn)); } $sql = "SELECT first_id, first_name FROM first"; $sql = "SELECT sum(total) as SumTotal FROM second"; $result = mysqli_query($conn, $sql); while ($data = mysqli_fetch_array($result)) { echo '<tr>'; echo '<th>'.$data['first_id'].'</th>'; echo '<th>'.$data['first_name'].'</th>'; echo '<th>'.$data['SumTotal'].'</th>'; echo '</tr>'; } mysqli_close($conn); Thanks!
  2. Hi everyone, I am still learning to do PHP, please be patient with me. Thank you so much! I am trying to understand how "while loop" work in PHP, or do you recommend me use foreach, for, or do for array list from MySQL database? my Code in PHP: <!doctype html> <html> <head> <title>Test foreach columns</title> <link href="default.css" rel="stylesheet" type="text/css"> </head> <body> <?php $Garydb = mysqli_connect("XXXXXX","XXXXXX","XXXXXX") or die("Could not connect MySQL Database"); mysqli_select_db($Garydb, "XXXXXX") or die("Could not find Database"); $sql = "SELECT * FROM XXXXXX"; $display = mysqli_query($Garydb, $sql); while($key = mysqli_fetch_array($display)) { echo "<table><tr><td>".$key."</td><td>".$key."</td></tr></table>"; } ?> </body> </html> seem display on website showing "Array Array" 12 row and 2 columns, what I did do wrong?
  3. Hello so I have a simple code here that will check if a random number already exists in the database and will generate a new one: $rand = mt_rand(100000, 999999); $sid = array( ":sponsorID" => $rand ); $accounts = $db->select("accounts", "sponsorID = :sponsorID", $sid) while(count($accounts) > 0) { $newNum = mt_rand(100000, 999999); } What I wanted to do is to echo out $newNum. When I echo it out I get undefined index of that variable. How can I solve this?
  4. <?php function getFullMonthName($num) { if ($num < 1 || $num > 12) { return "Unknown"; } return ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"][$num - 1]; } $ids = mysqli_real_escape_string($db, $id); $sql = "SELECT * FROM multimedia, keertan WHERE multimedia.id LIKE '$ids' AND keertan.multimediaid LIKE '$ids' ORDER BY k_order ASC"; $result = mysqli_query($db, $sql); $title_list = "xyz"; $done = "xyz"; while ($myrow = mysqli_fetch_array($result)) { $location = $myrow["location"]; $program = $myrow["program"]; $year = sprintf("%04s", $myrow["year"]); $month = sprintf("%02s", $myrow["month"]); $monthName = getFullMonthName($month); $isnew = $myrow["isnew"]; if ($done != "true") { echo "<h3><b>$location $program $monthName $year</b></h3>"; } $done = "true"; while ($title_list != $myrow["title"]) { $title_list = $myrow["title"]; $sublist = $myrow["sub_title"]; echo "<div class=\"panel panel-primary\"><div class=\"panel-heading clickable\"><h3 class=\"panel-title\"><b>$title_list</b></h3>"; echo "<small>$sublist</small><span class=\"pull-right\"><i class=\"fa fa-minus\"></i></span></div><div class=\"panel-sarabveer-table\"><table class=\"table\"><thead><tr><th>Time</th><th>Kirtani</th><th>MP3</th><th>Video</th></thead>"; } if (strtotime($myrow["created"]) > strtotime("3 weeks ago")) { $newed = "NEW"; } elseif (strtotime($myrow["modified"]) > strtotime("3 weeks ago")) { $newed = "UPDATED"; } else { $newed = ""; } printf("<tr><td>%s</td><td>%s <small>%s</small></td>", $myrow["length"], $myrow["keertaneeya"], $newed); $mp3f = urlencode($myrow['mp3_link']); if ($myrow["mp3_link"] != "") { printf("<td><a target=\"_blank\" href=\"http://www.akji.org.uk/multimedia/%s/%s/%s\"><img src=\"images/play.png\" border=\"0\" width=\"25\" height=\"25\"></a></td>", $myrow["location"], $year, $mp3f); } else { echo "<td></td>"; } if ($myrow["rv1_link"] != "") { printf("<td><a target=\"_blank\" href=\"%s\"><img src=\"images/vplay.png\" border=\"0\" width=\"25\" height=\"25\"></a></td></tr>", $myrow["rv1_link"]); } else { echo "<td></td></tr>"; } echo "</table></div></div>"; } ?> So Basically I have this code that displays this page: https://akjmobile.org/keertannew.php?id=532 The problem is that the echo on line 97 runs to early and cuts of rest of the table information, making the other table information be spit out outside of the Bootstrap Panel. How would I fix this?
  5. <?php function factorial($number) { if ($number < 2) { return 1; } else { return ($number * factorial($number-1)); } } function poisson($occurrence,$chance) { $e = exp(1); $a = pow($e, (-1 * $chance)); $b = pow($chance,$occurrence); $c = factorial($occurrence); return $a * $b / $c; } $x = 2.5; $y = 1.5; $calAll = array(); for($z = 0 ; $z <= 9 ; $z++) { array_push($calAll, (poisson($z,$x) * poisson(0,$y))*100, (poisson($z,$x) * poisson(1,$y))*100, (poisson($z,$x) * poisson(2,$y))*100 ); } $value = max($calAll); $key = array_search($value, $calAll); print_r($calAll) . "\n"; echo "max =",$value , " key =",$key . "\n";; ?> it is possible to find $z and the number 0,1 or 2 from the max of the returned array ? I used excel to perform this action and i found that for max=8.5854557290941 the $z is 2 and number 1 how to achieve this in php ?
  6. Hi, I have a json data, below which contains an item with tax: "date": "2015-05-05 12:41", "shop": "Toto", "products": [ { "price": "2.00", "quantity": "1", "description": "chocolat", "tax": [ { "price": "1.00", "quantity": "1", "description": "tax1" }, { "price": "2.00", "quantity": "1", "description": "tax2" } ] } ] } I am able to calculate the price ($amountAll) with the following code: $datajs = "myJsonSimple2.json"; $datajs = file_get_contents($datajs); $decodageDatajs = json_decode($datajs); $dateBiling = $decodageDatajs->date; $shopName = $decodageDatajs->shop; foreach ($decodageDatajs->products as $obj) { $ItemPrice = $obj->price; $ItemQuantity = $obj->quantity; $ItemDescription = $obj->description; $taxes = (array)$obj->tax; $taxesPrice1 = !empty($taxes[0]) ? $taxes[0]->price : 0.00; $taxesPrice2 = !empty($taxes[1]) ? $taxes[1]->price : 0.00; $taxesQuantity1 = !empty($taxes[0]) ? $taxes[0]->quantity : 0; $taxesQuantity2 = !empty($taxes[1]) ? $taxes[1]->quantity : 0; $taxesDescription1 = !empty($taxes[0]) ? $taxes[0]->description : '1er tax null'; $taxesDescription2 = !empty($taxes[1]) ? $taxes[1]->description : '2e tax null'; $amountAll = $ItemPrice * $ItemQuantity + $taxesPrice1 + $taxesPrice2; } But how I calculate if there are several items (2 or 3 or 5...) { "date": "2015-05-05 12:41", "shop": "Toto", "products": [ { "price": "2.00", "quantity": "1", "description": "chocolat", "tax": [ { "price": "1.00", "quantity": "1", "description": "tax1" }, { "price": "2.00", "quantity": "1", "description": "tax2" } ] }, { "price": "3.00", "quantity": "1", "description": "bonbon", "tax": [ { "price": "2.00", "quantity": "1", "description": "tax1" }, { "price": "3.00", "quantity": "1", "description": "tax2" } ] }, { "price": "2.00", "quantity": "1", "description": "gateaux", "tax": [ { "price": "1.00", "quantity": "1", "description": "tax1" }, { "price": "2.00", "quantity": "1", "description": "tax2" } ] } ] } I need like as : $amountAll = $ItemPrice1 * $ItemQuantity1 + $ItemPrice2 * $ItemQuantity2 + $ItemPrice3 * $ItemQuantity3 + $taxesPrice1a + $taxesPrice2a + $taxesPrice1b + $taxesPrice2b + $taxesPrice1c + $taxesPrice2c; but this is wrong : I must counter and use while statement but I don,t know how I can write ? $calculeItems = count($decodageDatajs->products); $i = 0; while ($i < $calculeItems) { foreach ($decodageDatajs->products as $obj) { $ItemPrice = $obj->price; $ItemQuantity = $obj->quantity; $ItemDescription = $obj->description; $taxes = (array)$obj->tax; $taxesPrice1 = !empty($taxes[0]) ? $taxes[0]->price : 0.00; $taxesPrice2 = !empty($taxes[1]) ? $taxes[1]->price : 0.00; $taxesQuantity1 = !empty($taxes[0]) ? $taxes[0]->quantity : 0; $taxesQuantity2 = !empty($taxes[1]) ? $taxes[1]->quantity : 0; $taxesDescription1 = !empty($taxes[0]) ? $taxes[0]->description : '1er tax null'; $taxesDescription2 = !empty($taxes[1]) ? $taxes[1]->description : '2e tax null'; $amountAll = $ItemPrice * $ItemQuantity + $taxesPrice1 + $taxesPrice2; /* this si wrong !!!!! $amountAll = $ItemPrice1 * $ItemQuantity1 + $ItemPrice2 * $ItemQuantity2 + $ItemPrice3 * $ItemQuantity3 + $taxesPrice1a + $taxesPrice2a + $taxesPrice1b + $taxesPrice2b + $taxesPrice1c + $taxesPrice2c; */ } $i++; } can you help me please Thanks
