hi. i am making mcq type test. lot of questions stored in db, i want that some of them retrieve i.e. 5 after 5 test should end. how is hould do,
query is ...SELECT question,questionid, choice1, choice2, choice3, choice4, answer FROM questionbank order by RAND() limit 1";... limit 1 is used for display one question in a page. Similar TutorialsHi, What I'm trying to do is create a script that generates a random list of cars whenever it is run. I have a list of available cars in a MySQL database. I'm just not sure how to get php to generate a list of, say, 20 cars, that are randomly picked from the cars in the database. I may also want to add other statistics like MPG (also already in the database). Can anyone show me how to do this? And is it possible to format the returned data in a table or div format? Thanks in advance Unk Hey everyone. I am creating a website so my family can select from the list of present my daugther has asked for. I have them logging in, and that works. I have the table data set and the search and table display works. But I would like to display the list (as in the code below) but with a checkbox in the first column (add a column). From that the authenticated user can click on the item they have purchased and that selection will be moved to another table (called purchased). I have that code. The only thing I cannot figure out is to present the data in list form with a checkbox (like you would see on an order form). Here is the display code (there is no error checking at this point): <head><LINK REL="SHORTCUT ICON" HREF="cmwschl.ico"></head> <body bgcolor="#C0C0C0"> <font face="Arial" color="#000080">Books from the Selected Series</font> </h1> <hr font color="Navy" font size="3"> <center> <table border="1" cellpadding="5" cellspacing="0" bordercolor="#000000"> <tr> <td width="170" bgcolor="#FFCC66"><center><b><font color="navy" size="2" face="Trebuchet MS"><b><center>Book Number</center></font></b></center></td> <td width="140" bgcolor="#FFCC66"><center><b><font color="navy" size="2" face="Trebuchet MS"><b><center>Book Group</center></font></b></center></td> <td width="100" bgcolor="#FFCC66"><center><b><font color="navy" size="2" face="Trebuchet MS"><b><center>Book Title</center></font></b></center></td> </tr> <?php $con = mysql_connect("localhost","twilson","R00tb33r!") or die('Connection: ' . mysql_error());; mysql_select_db("CMWWeb", $con) or die('Database: ' . mysql_error()); ?> <?

Any help? AS far as my understanding i have selected it as "Contactinfo"? Thanks Danny Hey guys, im trying to make a dropdown box get a selected value based on the value from multiple rows. Here is what im trying to do: <?php // select the value from the database // $value = ... ?> <form action="..."> <option value="1"<?php if ($value == 1) { echo ' selected="selected"'; } ?>>First</option> <option value="2"<?php if ($value == 2) { echo ' selected="selected"'; } ?>>Seccond</option> <option value="3"<?php if ($value == 3) { echo ' selected="selected"'; } ?>>Third</option> <input type="submit"> </form> The thing is I have no idea what to put at the top and how to assign the $value part. Here is my current code. <?php mysql_connect("localhost", "", "")or die("cannot connect"); mysql_select_db("test")or die("cannot select DB"); $tbl_name="test_mysql"; $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $count=mysql_num_rows($result); // MOVED this code to the top before you output anything if (isset($_POST['Submit'])) { for($i=0;$i<$count;$i++){ $month = $_POST['month']; $date = $_POST['date']; $message = $_POST['message']; $title = $_POST['title']; $id = $_POST['id']; $icon = $_POST['icon']; // ILYA $monthday= $month[$i]."<br>".$date[$i]; $sql1="UPDATE $tbl_name SET monthday='$monthday', month='$month[$i]', date='$date[$i]', message='" . mysql_real_escape_string($message[$i]) .

I dont want it to like interfere. Do you kinda know what I mean? Also, heres hows the database looks like. Picture of webpage. Here is the full code if anyone would like to see: <?php mysql_connect("localhost", "", "")or die("cannot connect"); mysql_select_db("test")or die("cannot select DB"); $tbl_name="test_mysql"; $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $count=mysql_num_rows($result); // MOVED this code to the top before you output anything if (isset($_POST['Submit'])) { for($i=0;$i<$count;$i++){ $month = $_POST['month']; $date = $_POST['date']; $message = $_POST['message']; $title = $_POST['title']; $id = $_POST['id']; $icon = $_POST['icon']; // ILYA $monthday= $month[$i]."<br>".$date[$i]; $sql1="UPDATE $tbl_name SET monthday='$monthday', month='$month[$i]', date='$date[$i]', message='" . mysql_real_escape_string($message[$i]) .

I have an audio mix submitting form on my website. The first part of the form takes the details from the user and inserts a new row in the first table 'mix', auto incrementing to generate a mix_id primary key. The second part then uses a series of check boxes to select which genres the mix contains and a foreach for the resulting array to insert, into the 2nd table 'genres_for_mix', a new row for each genre id (foreign key for the genres table) that is selected and the mix_id that it concerns. Now I'm starting to think this is a bad way to do this because: 1. I don't know how to echo this out when a user edit's the mix to make all the relevant checkboxes selected. 2. When a user deselects a choice, it would be quite long winded to delete the nessesary row. So instead I'm thinking that it would be much wiser to user the serialise functions to put the array into the database However, I still don't know how to make the right checkboxes selected when I echo out the edit form. Do I use something like inarray()? If so how? Also, it's really important that I can query the database for mixes that are associated with a specific genre. Without unserialising the array and therefore echo'ing out all the results, I don't know how to query this. Would I just use a 'WHERE genre_field LIKE 'genre_id'? Can anyone help me with this please? Hi, I am new to php and need help. I am building a library system for an assignment. I want to provide a functionality that registers (adds) all transactions to defferent databases. I am stuck on how to add a selected row (selected by a checkbox) to the database and make sure that 2 users cannot update the same record at the same time.

Thanks for any help, hope you understand what im trying to explain Hello to all, I have problem figuring out how to properly display data fetched from MySQL database in a HTML table. In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table. The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'
Can someone help me on this, I guess the problem lies in the while loop? <thead> <tr> <th data-column-id="id" data-type="numeric">ID</th> <th data-column-id="email">Subscriber's Email</th> <th data-column-id="validity">Validity</th> <th data-column-id="valid_from">Valid From</th> <th data-column-id="valid_to">Valid To</th> </tr> </thead> Here is part of the PHP code:
<?php
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
echo '
<tr>
<td>'.$row["id"].'</td>
';
while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
echo '
<td>'.$row1["email"].'</td>
';
}
if($row["validity"] == 1) {
echo '<td>'.$row["validity"].' month</td>';
}else{
echo '<td>'.$row["validity"].' months</td>';
}
echo ' <td>'.$row["valid_from"].'</td>
<td>'.$row["valid_to"].'</td>
</tr>';
}
?>
Thank you. I have a page which displays an item based on a search. Below is the code. Code: [Select] <?php error_reporting(E_ALL ^ E_NOTICE); ini_set("display_errors", 1); require ('includes/config.inc.php'); include ('./includes/header.html'); require (MYSQL); include ('./includes/main.html'); if($id = isset($_GET['prodID'])) { $query = "SELECT `prodID`, `product`, `prod_descr`, `image`, `price` FROM product WHERE `prodID`='{$_GET['prodID']}'"; $r = mysqli_query($dbc, $query); $showHeader = true; echo "<div id='right'>"; while($row = mysqli_fetch_array($r)) { if($showHeader) { //Display category header echo "<h1>" . "<span>" . "# " . "</span>" . $row['product'] . "<span>" . " #" . "</span>" . "</h1>"; echo "<div id='item'>"; // div class 'item' echo "<div class='item_left'>"; echo "<p>"; echo $row['prod_descr']; echo "</p>"; echo "<p>"; echo "£" . $row['price']; echo "</p>"; echo "</div>"; echo "<div class='item_right'>"; echo "<img src='db/images/".$row['image']."' />"; $showHeader = false; echo "<br />"; echo "You may also like...."; echo $row['product']; echo "</div>"; } } ?> <p> <form target="paypal" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="cmd" value="_s-xclick"> <input type="hidden" name="item_name" value="<?php echo $row['product']; ?>"> <input type="hidden" name="item_number" value="<?php echo $row['prodID']; ?>"> <input type="hidden" name="amount" value="<?php echo $row['price'] ?>" /> <input type="hidden" name="currency_code" value="GBP"> <input type="hidden" name="hosted_button_id" value="7UCL9YCYYXL3J"> <input type="image" src="https://www.sandbox.paypal.com/en_US/i/btn/btn_cart_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!"> <img alt="" border="0" src="https://www.sandbox.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1"> </form> </p> <?php echo "</div>"; // End of div class 'item' echo "</div>"; } include ('./includes/footer.html'); ?> What I want to achieve is just below the product content, is a feature with one or two random records which will essentially say to the user "you may also like" and display random but similar products. How do I achieve this? |
