PHP - Mysql_num_rows And Select Menu

the same page?

Hi there,
i am relatively new to php, mysql, css etc but learning fast.
My problem is such;
i have a php file which is doing a SELECT mysql_query, WHILE results to strings, then ECHO the resulting rows to produce a list  formatted using  <table> and finally this <table> is inside a <form> which will POST the  changes back to the specific database.tble.row.

I wish to have a drop down menu within the <form><table> which will be populated from a separate database.table.

I have accomplished the drop down menu outside the <?php ?> tags inside  <form><table> which POSTS to a php file but my problem is to add the populating drop down menu inside <?php ?> an already ECHOing resulting rows from the sql query.

 i.e <?php blurb and stuff ?>
<form><table><tr><td>
<select name etc>
<?php
$result = mysql_query("SELECT * FROM tbl WHERE string = tble.rw ORDER BY column");
while($row=mysql_fetch_array($result)){
echo "<OPTION VALUE=".$row['column'].">".$row['column']."</OPTION>";
}
?>
</select> WORKS!!!!

but placing this inside

<?php $x =mysql_query[select] while {strings = conditions; echo ("<form><table><tr><td>
insert populated drop menu here
</td> etc ");
echo"";}?>

doesnt work and just leaves the select drop menu blank

Hoep you understand my problem.
I do not think i can attached the population WHILE loop to a string and just insert the string to the form but maybe i am wrong.

thanks in advance and if you go tthis far reading you must be on lots and lots of coffee

hello all, I was hoping someone could help me figure out how to add sizes to my shopping cart.
Right now the items add just fine. The site sells shirts and I'm having trouble displaying the sizes once selected and added to the cart. It will post the size selected, but if the customer tries to add another shirt the size will overwrite the last.

Any help is appreciated.

Heres how I add items to the cart...
Code: [Select]
session_start();
// Process actions
$cart = $_SESSION['cart'];
$action = $_GET['action'];
switch ($action) {
case 'empty':
if($cart) {
unset($cart);
}
break;
case 'add':
if ($cart) {
$cart .= ','.$_GET['product_id'];
} else {
$cart = $_GET['product_id'];
}
break;
The form with the size selection and add to cart button..
Code: [Select]
  <form action="cart.php?action=add&amp;product_id=<?php echo $row_rs_products['product_id'] ?>" method="POST" name="addcart" id="addcart">
      <table width="300" border="0">
        <tr>
          <td><label for="sizes"></label>
            <select name="product_size" id="product_size" title="<?php echo $row_rs_products['product_size']; ?>">
              <?php
do {  
?>
              <?php
} while ($row_rs_sizes = mysql_fetch_assoc($rs_sizes));
  $rows = mysql_num_rows($rs_sizes);
  if($rows > 0) {
      mysql_data_seek($rs_sizes, 0);
  $row_rs_sizes = mysql_fetch_assoc($rs_sizes);
  }
?>
            </select></td>
          <td><input type="submit" name="submit" id="submit" value="add to cart">
function displaying the cart..
Code: [Select]
function showCart() {
global $db;
$cart = $_SESSION['cart'];
if ($cart) {
$items = explode(',',$cart);
$contents = array();
foreach ($items as $item) {
$contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1;
}
$output[] = '<form action="cart.php?action=update" method="post" id="cart">';
$output[] = '<table>';
// start div
$output[] = '<div id="cart_table">';
//
$output[] = '<tr>';
$output[] = '<td><h4>Product</h4></td>';
$output[] = '<td><h4>Item No.</h4></td>';

$output[] = '<td><h4>Price Total</h4></td>';
$output[] = '<td><h4>&nbsp;</h4></td>';
$output[] = '</tr>';
//new row
foreach ($contents as $product_id=>$qty) {
$sql = 'SELECT * FROM products WHERE product_id = '.$product_id;
$result = $db->query($sql);
$row = $result->fetch();
extract($row);
//
$output[] = '<tr>';
$output[] = '<td><a href="product.php?product_id='.$product_id.'">'.$product_title.'</a></td>';
$output[] = '<td>'.$product_plu.'</td>';
$output[] = '<td>$'.$product_price.'</td>';
//
//$output[] = '<td>'.$product_size.'</td>';
$output[] = '<td>'.$_POST['product_size'].'</td>';
//
$output[] = '<td><input type="text" name="qty'.$product_id.'" value="'.$qty.'" size="3" maxlength="3" /></td>';
$output[] = '<td>X&nbsp;$'.($product_price * $qty).'</td>';
$total += $product_price * $qty;
$output[] = '<td><a href="cart.php?action=delete&product_id='.$product_id.'" class="r">Remove</a>&nbsp;</td>';
$output[] = '</tr>';
//end div
$output[] = '</div>';



}

I'll really appreciate your help.

Hi, Im not sure whether this is a PHP or MySQL question, but im trying to get a select menu to only display the number of options that are defined in the mysql database.   For example   The code I have that retrieves the $quantity from the database.   Lets say that   $quantity = 3   Now I would like the option menu to only display three options, like this:

<select name="quantity">
<option value="<?php echo $quantity ?>"><?php echo 'Maximum of ' . $quantity . ' available'?></option>
<option value="1">1</option> 
<option value="2">2</option>
<option value="3">3</option>
</select>

but for example, if the $quantity was equal to 10 then I would like the menu to be displayed as such

<select name="quantity">
<option value="<?php echo $quantity ?>"><?php echo 'Maximum of ' . $quantity . ' available'?></option>
<option value="1">1</option> 
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
</select>

How is it possible to do this? I am completely at a loss here.   Many Thanks   aquaman

Hi.
Maybe a tricky question?

How do I reflect the content of a column from a database table in a roll down select menu in the browser?

Let's say that the content of the table column is:

Anna
Michael

These names should be reflected in this select menu like this:

<select name="friends">
<option value="Choose a name">Choose a name</option>
<option value="Anna">Anna</option>
<option value="Michael">Michael</option>

So visitors can choose a name, and thereby turn it into a variable, for reuse in the database.

Best regards Morris

I am working on a project where I want a select form to display information from a MySQL table. The select values will be different sports (basketball,baseball,hockey,football) and the display will be various players from those sports. I have set up so far two tables in MySQL. One is called 'sports' and contains two columns. Once called 'category_id' and that is the primary key and auto increments. The other column is 'sports' and contains the various sports I mentioned. For my select menu I created the following code.


<?php
#connect to MySQL
$conn = @mysql_connect( "localhost","uname","pw")
or die( "You did not successfully connect to the DB!" );

#select the specified database
$rs = @mysql_SELECT_DB ("test", $conn )
or die ( "Error connecting to the database test!");
?>

<html>
<head>Display MySQL</head>
<body>
<form name="form2" id="form2"action="" >
<select name="categoryID">
<?php
$sql = "SELECT category_id, sport FROM sports ".
"ORDER BY sport";

$rs = mysql_query($sql);

while($row = mysql_fetch_array($rs))
{
  echo "<option value=\"".$row['category_id']."\">".$row['sport']."</option>\n  ";
}
?>
</select>

</form>
</body>
</html>




this works great. I also created another table called 'players' which contains the fields 'player_id' which is the primary key and auto increments, category_id' which is the foreign key for the sports table, sport, first_name, last_name.

The code I am using the query and display the desired result is as follows


<html>
<head>
<title>Get MySQL Data</title>
</head>
<body>
<?php
#connect to MySQL
$conn = @mysql_connect( "localhost","uname","pw")
or die( "Err:Db" );

#select the specified database
$rs = @mysql_SELECT_DB ("test", $conn )
or die ( "Err:Db");

#create the query
$sql ="SELECT *
FROM sports
INNER JOIN players ON sports.category_id = players.category_id
WHERE players.sport = 'Basketball'";

#execute the query
$rs = mysql_query($sql,$conn);

#write the data
while( $row = mysql_fetch_array( $rs) )
{
echo ("<table border='1'><tr><td>");
echo ("Caetegory ID:  " . $row["category_id"] );
echo ("</td>");
echo ("<td>");
echo ( "Sport: " .$row["sport"]);
echo ("</td>");
echo ("<td>");
echo ( "first_name: " .$row["first_name"]);
echo ("</td>");
echo ("<td>");
echo ( "last_name: " .$row["last_name"]);
echo ("</td>");
echo ("</tr></table>");
}
?>
</body>
</html>





this also works fine. All I need to do is tie the two together so that when a particular sport is selected, the query will display below in a table. I know I need to change my WHERE clause to a variable. This is what I need help with.

thanks

Hi

I am trying to create a login script using the code below

Code: [Select]
<?php
session_start();
include_once('includes/connect.php');
$user=$_POST['username'];
$password=$_POST['password'];
//check if username and password exists
$checkuser=mysql_query("SELECT * from `tbl_users` where username = '$user' and password=md5('$password')");
if(mysql_num_rows($checkuser) > 0) //login name was found
//if they do return to home page with relevant include
{
  $user_row = mysql_fetch_array($checkuser);
  $_SESSION['auth']="yes";                    
     $_SESSION['logname'] = $user_row['forename']; 
  $_SESSION['usertype'] = $user_row['usertype'];
  header("Location: index.php");
      exit;
  }
//if not display login form with message that says logon details are incorrects
else
{
echo('Do something else');
}
?>

However I get a message saying that mysql_num_rows is not a valid resource.

Any ideas where I am going wrong?

I'm trying to loop out 10 rows of comment, but this code only displays comment one time, how do I display all rows?


$query = "SELECT * FROM ".$prefix."comments WHERE userto = '".$user."' ORDER BY comment DESC LIMIT 0, 10";
$result = mysql_query($query);
$num = mysql_num_rows($result);

//Loop out code
$i=0;
while ($i < $num) {
    $comments=@mysql_result($result,$i,"comment");
    $i++;
}

Hello,

I am having a problem..

I get this message " Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in... " whenever i am trying to work my log in script.

$result=mysql_query($sql);

$count= mysql_num_rows($result); <----------- problem

if ($count == 1)

Is there any simpler way to create a log in page but being secure as well?

Thank in advance.

	$total = mysql_num_rows($query) or die ("E112-101A");

Hi I have a website with a few users. I set up a system so that some users (as a trial) can only log on a fixed number of times. I have a field called current that counts down to zero. However when it reaches zero I get my error E112-101A   Why do I get an error? Surely I should just get $total = 0      

I am currently creating a form and I want to populate a drop down selection menu with data from two fields in a form. For example, I want it to pull the first and last name fields from a database to populate names in a drop down menu in a form. I want the form to submit to the email address of the person selected in the drop down. Is this possible to do? The email is already a field in the record of the person in the database.

Can anyone give me some pointers or advice on how I should go about setting up the "Select" box drop down? I am not sure how to code it to do what I am wanting. Any links to relevant help would be appreciated too.

Thanks in advance!
