I had develop a simple quiz system that allow user generate random question from database. I had use array shuffle to do the random question. My problem is every time when I submit the form, the array will shuffle. Now what I want is I want to stop the shuffle when i submit the form.
<?php
$ques_ar = array();
$ques = mysql_query("Select * from quiz");
while($row = mysql_fetch_array($ques))
{
$ques_ar[] = $row;
}
shuffle($ques_ar);
echo '<form method="post">';
for ($i=0; $i<sizeof($ques_ar); $i++)
{
echo ".$ques_ar[$i]['question']."?<br>";
$a=array($ques_ar[$i]['answer'],$ques_ar[$i]['dummy_ans1'], $ques_ar[$i]['dummy_ans2'], $ques_ar[$i]['dummy_ans3']);
shuffle($a);
foreach($a as $ram => $value)
{
$alp = array("A","B","C","D");
echo "<input type='radio' name='".$i."' value='".$value."'>".$alp[$ram]." (".$value.")<br>";
}
if(isset($_POST[$i]))
{
if($_POST[$i] == $ques_ar[$i]['answer'])
{
echo "Correct !<br>";
$score = 1;
}else{
echo "Wrong ! <br>";
$score = 0;
}
}
$total +=$score;
}
echo "<input type='submit' name='sub_ans'>";
echo '</form>';
echo "Score => ".$total." / ".sizeof($ques_ar);
?>

I have a form, populated by an uploaded CSV, and upon submit it saves to my database staging/temp table. However, it's only saving the first 4 of 7 rows.
The form:
$file = $_FILES["file"]["tmp_name"];
$handle = fopen($file, "r");
$maxPreviewRows = PHP_INT_MAX; // this will be ~2 billion on 32-bit system, or ~9 quintillion on 64-bit system
$hasHeaderRow = true;
echo "<form method='post' action='/form-submit' >";
echo '<table>';
/*WE WILL NEED TO QA CONDITIONS AND HIGHLIGHT IN RED HERE. ALSO NEED BORDER STYLINGS*/
if ($hasHeaderRow) {
$headerRow = fgetcsv($handle);
echo '<thead><tr>';
foreach($headerRow as $value) {
echo "<th>$value</th>";
}
echo '</tr></thead>';
}
echo '<tbody>';
$rowCount = 0;
while ($row = fgetcsv($handle)) {
$colCount = 0;
echo '<tr>';
foreach($row as $value) {
echo "<td><input name='row[".$rowCount."][".$colCount."]' type='text' value='$value' /></td>";
$colCount++;
}
echo '</tr>';
if (++$rowCount > $maxPreviewRows) {
break;
}
}
echo '</tbody></table>';
echo "<input type='submit' name='confirm' value='confirm'>";
echo '</form>';
}
The submission:
foreach ($_POST['row'] as $rowValue)
{
if( is_array($rowValue) && count($rowValue) > 0 )
{
$sqlFull = "INSERT INTO staging VALUES( DEFAULT, ". substr( str_repeat ( '?, ', count($rowValue) ), 0, -2 ) .")";
if( !$stmt = $connect->prepare($sqlFull) )
{
echo "Prepare failed: (" . $connect->errno . ") " . $connect->error;
}
$stmt->bind_param( str_repeat ( 's', count($rowValue) ), ...$rowValue );
$stmt->execute();
}
}
So it's definitely working but for some reason it's stopping on the fourth row every time. I edit the first field of each row each time and when I check my file dashboard I'll see only the first 4 from each submission.
ANy ideas why this is ending on the 4th row?
UPDATE:
I have a table in the database named 'transactions'. I want to list out the values from this table. The result should be displayed in HTML table format. The rows in the resulted table should be grouped as per the amount.There is a column named 'amount' in the 'transactions' table.
Here is my code:
$s1 = DB::table('transactions')
->select(DB::raw("GROUP_CONCAT(selected_seats SEPARATOR '') as selected_seats"),'userid','amount','show_id')
->where("show_id","=",$s)
->groupBy('userid')
->groupBy('amount')
->orderBy('userid','ASC')
->orderBy('amount', 'DESC')
->get();
I am retrieving the values from $s1 variable through loop.
Following is the output:
and i want the result like this:
Please click on the links given above. I am new to this forum so its not allowing me to add images in the question. Kindly help.
Here is the entire code:
if($s1 != null)
{

Easiest way I think is calculate amounts in the loop you are printing data or readying data to send to a view. Since your data sorted by user_id, you always can change amount variable in the loop when user_id is changing. You can use count(explode($seat_variable)) to get number of seats in a single run of the loop. Look at the example code below.
$num_seat = 0; $amount = 0; $running_user_id = -1;
foreach ($row as $entry) {
...
if ($running_user_id != $entry['user_id']) { // check if the same user
$running_user_id = $entry['user_id'];
$num_seat = 0; $amount = 0; // resetting variable values for seperate user.
}
$num_seat += count(explode($entry['selected_seats']));
$amount += $entry['amount'];
...
}
And I assume you have missing data like emails in the query.
Code update after questioner added his code.
if($s1 != null) {
echo "<div class='panel-body'>";
echo "<table class='table table-responsive'>"; $c = 1;
echo "<tr>";
echo "<th>Drama Title</th>";
echo "<th>Show Date</th>";
echo "<th>Seat booked</th>";
echo "<th>Amount</th>";
// echo "<th>User</th>";
echo "</tr>";
$category = ""; $num_seats = 0;
for ($i=0; $i<count($s1); $i++) {
if ($category != $amount) {
if ($i > 0) { // print totals
echo "<tr>
<td colspan='3' align='right'>Total</td>
<td>".$num_seats."</td>
<td>".($num_seats * $amount)."</td>
</tr>";
echo "<tr><td colspan='5'> </td></tr>"; // empty row after totals printed
$num_seats = 0; //resetting number of seats per category
}
echo "<tr><td colspan='5'><h2>Category : ".$amount."</h2></td></tr>"; // printing category line in the given table
$category = $amount; // this logic is to prevent category line printing for each row
}
$transactions = DB::table('transactions')->where('userid',$s1[$i]->userid)->where('show_id',$s1[$i]->show_id)->get();
echo "<tr>";
$users = DB::table('users')->where('id', $s1[$i]->userid)->get();
// Check below values are correct or not
echo "<td>".$users[0]->name."</td>";
echo "<td>".$s1[$i]->userid."</td>";
echo "<td>".$s1[$i]->email."</td>"; // get user's email property here
echo "<td>".$s1[$i]->selected_seats."</td>";
$num_seats += count(explode(',', $s1[$i]->selected_seats));
echo "<td> </td></tr>"; // empty colomn for amount and the row end
}
echo "</table>";
echo "</div>";
}
My website currently ignores the first two images you place into the database and then proceeds to add images going across 5 columns and then moving down to the next row.
Update: Now it shows 3 of the 4 images in the database. Skips one image.
<?php
$i = 1;
echo "<table>";
while ($row = $Recordset2->fetch_object()) {
if ($i == 1) {
echo "<tr>";
}
echo '<td><img src="'.$row_Recordset2['ImgSource'].'" width="100" height="100"></td>';
if ($i == 5) {
$i = 1;
echo "</tr>";
} else {
$i++;
}
}
echo "</table>";
?>
This is what my database looks like
http://i.stack.imgur.com/IFba8.jpg
This is what my website shows
http://i.stack.imgur.com/Wf7E1.jpg
Try this:
<?php
$i = 1;
echo "<table>";
while ($row = $Recordset2->fetch_object()) {
if ($i == 1) {
echo "<tr>";
}
echo '<td><img src="'.$row['ImgSource'].'" width="100" height="100"></td>';
if ($i == 5) {
$i = 1;
echo "</tr>";
} else {
$i++;
}
}
echo "</table>";
?>
Please try this.
<?php
$i = 1;
echo "<table>";
while ( $row = $Recordset2->fetch_object() ) {
if ($i == 1) {
echo "<tr>";
}
echo '<td><img src="'.$row_Recordset2['ImgSource'].'" width="100" height="100"></td>';
if ($i == 5) {
$i = 1;
echo "</tr>";
} else {
$i++;
}
}
echo "</table>";

<?php
$result10=mysql_query("SELECT * FROM blog_articles WHERE fk_semikatagori_id = 9") or die(mysql_error());
?>
<?php
$index = 1;
while($row10 = mysql_fetch_array($result10)) {
if($index%2==0) {
echo "<span class=\"f\">";
echo $row10['english_navn'];
echo "</span><br />";
}
else {
echo "<p><span class=\"f\">";
echo $row10['english_navn'];
echo "</span></p><br />";
echo "<p>";
echo $row10['english_tekst'];
echo "</p><br />";
}
$index++;
}
?>
Any ideas how I can display the number for each row?
I want it to start from 1.
I cant display the id from Mysql because it doesnt start from 1.
You could for example use a for() loop instead of a while() loop,
for ($index = 0; $row10 = mysql_fetch_array($result10); $index++)
{
...
echo $index;
}
Then the counter would be echoed.
$index = 1;
while( $row = mysql_fetch_array($result) )
{
// display the number for each row
echo $index;
// other code...
// increment number
$index++;
}
Thanks everyone for the help, it worked.
Here is the code if anyone else can use it.
<?php
$index = 1;
for ($index2 = 1; $row10 = mysql_fetch_array($result10); $index2++)
{
if($index%2==0)
{
echo "<span class=\"f\">";
echo $row10['english_navn'];
echo $index2;
echo "</span><br />";
}
else
{
echo "<p><span class=\"f\">";
echo $row10['english_navn'];
echo "</span></p><br />";
echo "<p>";
echo $index2;
echo $row10['english_tekst'];
echo "</p><br />";
}
$index++;
}
?>
I think the best solution that you can get are the follow:
Make a for statement:
<?php
for($idx=1; $row = mysql_fetch_array($result10); $idx++) {
...
}
?>
as said before or use the follow:
<?php
$idx = 1;
while($row = mysql_fetch_array($result10)) {
...
$idx++;
}
?>
I would recommend you to make a like upgrade in your select statement to get a faster result (if you start get many rows as result):
from: SELECT * FROM blog_articles WHERE fk_semikatagori_id = 9
to:
SELECT
english_navn
, english_tekst
FROM blog_articles
WHERE
fk_semikatagori_id = 9
Because you are using just these 2 columns into your loop but you are making MySQL engine get all columns from this table.
I hope it help you.
I'm trying to allow a user to edit a row of their data with POST from a displayed form. The query is working and the table properly displays everything except a name value in the form input field. I've tried numerous variations but the name value keeps coming up blank. The problem might be with this line:
echo $field_name;
Here is the code:
<form action="process.php" method="POST">
<?
$qry = "SELECT activity, site, date, FROM home WHERE user_id='$session->user_id' ORDER BY date";
$res = mysql_query($qry);
$field_name = mysql_field_name($res, 0);
function mysql_fetch_all($res) {
while($row=mysql_fetch_array($res)) {
$return[] = $row;
}
return $return;
}
function create_table($dataArr) {
echo "<form action=\"process.php\" method=\"POST\"><table><tr>";
for($j = 0; $j < 3; $j++) {
echo "<td><input type=\"text\" name=\"";
echo $field_name;
echo "\" maxlength=\"30\" value=" .$dataArr[$j]. "></td>";
}
echo "<td><input type=\"hidden\" name=\"subedit\" value=\"1\"><input type=\"submit\" value=\"Update\"></td></tr></table></form>";
}
$all = mysql_fetch_all($res);
echo "<table class='data_table'>";
echo "<tr><td colspan=\"3\"><h2>Current Profile</h2></td></tr>";
echo "<tr><small><td>Activity </td><td>Site </td><td>Date </td></small></tr>";
for($i = 0; $i < count($all); $i++) {
create_table($all[$i]);
}
echo "</table></form>";
$field_name is out of scope (check out PHP's variable scope page). Try changing your create_table function to accept the $field_name var like so:
function create_table($dataArr, $field_name) {
...
}
...
for($i = 0; $i < count($all); $i++) {
create_table($all[$i], $field_name);
}
Or using global (not as recommended)
function create_table($dataArr) {
global $field_name;
...
}
Try this code:
<form action="process.php" method="POST">
<?
$qry = "SELECT activity, site, date, FROM home WHERE user_id='$session->user_id' ORDER BY date";
$res = mysql_query($qry);
$field_name = mysql_field_name($res, 0);
function mysql_fetch_all($res) {
while($row=mysql_fetch_array($res)) {
$return[] = $row;
}
return $return;
}
function create_table($dataArr, $field_name) {
echo "<form action=\"process.php\" method=\"POST\"><table><tr>";
for($j = 0; $j < 3; $j++) {
echo "<td><input type=\"text\" name=\"";
echo $field_name;
echo "\" maxlength=\"30\" value=" .$dataArr[$j]. "></td>";
}
echo "<td><input type=\"hidden\" name=\"subedit\" value=\"1\"><input type=\"submit\" value=\"Update\"></td></tr></table></form>";
}
$all = mysql_fetch_all($res);
echo "<table class='data_table'>";
echo "<tr><td colspan=\"3\"><h2>Current Profile</h2></td></tr>";
echo "<tr><small><td>Activity </td><td>Site </td><td>Date </td></small></tr>";
for($i = 0; $i < count($all); $i++) {
create_table($all[$i], $field_name);
}
echo "</table></form>";
However, I do recommend that you try to create a Table class. It would be much more efficient and neater.
