I have a map which shows sales people by location and if more then one sales person exists then I would need 2 pop up windows.   This works great other than the fact that the areas with one sales person are getting a blank 2nd popup as a second salesperson does not exist.   Any help would be appreciated.   Thanks In Advance

Hi,

I have a sign up form that generates a activation key and emails it to user and they cannot login until account has been activated etc.

My problem is i am not sure how to in php generate a new activation key if the generated one has already been used.

I know how to do the MySQL query to check if activation key already exists but not sure how to basically tell PHP that if the activation key already exists in DB then generate a new key until one is found that does not already exist.

I gather i may need a loop but not sure. Could someone please help ?

Like i say i know how to do the MySQL query just need some sample code to know how to do what i asked above.

Thanks for anyhelp; Much Appreciated

Maybe I am over thinking this, but I would like to see if their is another value after the current value without moving the internal array pointer. What can I do?

My error below returns (echos) that there is no data under the table sites to display. But, there is. Why is it doing this?

hello, have a question.  im trying to do a select * where id exists in array $id8

here is my array

Code: [Select]
$result8 = mysql_query("SELECT * FROM customers WHERE whosclient = 'Lansoft'");
while($row8 = mysql_fetch_array($result8))
{
$id8=$row8['id'];
}
here is my select code.  it is only returning results for the highest number in the array

Code: [Select]
$result = mysql_query("SELECT * FROM timesheets WHERE status = 3 AND billable = 1 AND client = '$id8' ORDER BY date, starttime");
while($row = mysql_fetch_array($result))
{
Thanks for any help!

If I do a mysql query from a database on a field that either has a number or is blank, how can I write php to check that. 

In other words, I am getting that value back into a variable called $isaresult and doing...
Code: [Select]
if ($isaresult !== '') {
//value exists
} else {
//no value yet
}
It's that first line of code that doesn't seem to be working. Should I be using "null" or something instead? 

I'm not real experienced with checking if a value exists, so let me know the proper way to do it (since I assume there are multiple ways).

Thanks!

Hi folks,

Working on something and I'm not sure how best to do it. It's a system whereby customers can login and see pdf files. Each customer has a unique reference number which is mirrored with a folder on the server, the folder name being the customer reference number. That's the first bit of checking. Then, within that customer folder there will be between 1 and X sub folders which are labelled by unique product reference numbers. Beyond that, each of the product reference folders will have a year folder with a folder for each month of the year going forward. Here's an example of the folder structu

- Customer Number (e.g. 12345678)
  - Product Number (e.g. 456789) (could be more than one)
    - Year (e.g. 2011) (could be more than one)
      -Month (e.g. 01/02/03/04/05/06 etc)

Essentially, I'm just unsure how to check if folders exist and display their contents if they do.

Here's my code so far, which does the first part of checking to see if the product numbers exist, but not the folder checking (I've not activated the hyperlinks in this code yet). This doesn't go as far as years and months yet, just the product number:

Code: [Select]
$query = mysql_query("SELECT * FROM customers where id = '$id'");
while($rst = mysql_fetch_array($query))

{ echo "$rst[company_name]"; }

$query = mysql_query("SELECT * FROM sites where company_name = '$company'");
while($rst = mysql_fetch_array($query))

{ echo "$rst[site]<br>";

if ($rst[product1] !== ""){
echo "- <a href='#'>$rst[product1]</a><br>";
}

if ($rst[product1] == ""){
echo "";
}

if ($rst[product2] !== ""){
echo "- <a href='#'>$rst[product2]</a><br>";
}

if ($rst[product2] == ""){
echo "";
}

if ($rst[product3] !== ""){
echo "- <a href='#'>$rst[product3]</a><br>";
}

if ($rst[product3] == ""){
echo "";
}

if ($rst[product4] !== ""){
echo "- <a href='#'>$rst[product4]</a><br>";
}

if ($rst[product4] == ""){
echo "";
}

if ($rst[product5] !== ""){
echo "- <a href='#'>$rst[product5]</a><br>";
}

if ($rst[product5] == ""){
echo "";
}

Code: [Select]
$result = mysql_query("SELECT field_item_id_value FROM `content_type_ads`");

while($row = mysql_fetch_array($result)){
   echo $row['field_item_id_value'];
   echo "<br />";
    echo $result;
}
I am trying to use an "array diff()" argument and I am getting errors with it stating the above is not an array.  I have used $row and $result, and neither work.  Is this not dumping into an array properly?

All,

In my registration script I am trying to check if an email address already exists (yawn I know), and I am stuck. The code highlighted in bold is where I want to check if the email exists (notice that form checking is done above that, including sorting out the email address that the user enters) and if it doesnt insert data into the table. Trouble is that on loading the page it simply states the 'already submitted' error before an email is even entered into the form:


Code: [Select]
         if(isset($_POST['name']) && !empty($_POST['name']) AND isset($_POST['email']) && !empty($_POST['email']) AND ($_POST['password']) && !empty($_POST['password'])){
        $name = mysql_escape_string($_POST['name']); // Turn our post into a local variable
        $email = mysql_escape_string($_POST['email']);
        $password = mysql_escape_string($_POST['email']);// Turn our post into a local variable
    }

$name = mysql_escape_string($_POST['name']);
$email = mysql_escape_string($_POST['email']);
$password = mysql_escape_string($_POST['password']);

if(!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)){
    // Return Error - Invalid Email
       $msg = 'The email you have entered is invalid, please try again.';
       
}else{
   // Return Success - Valid Email
$msg = 'Your account has been made, <br /> please verify it by clicking the activation link that has been sent to your email.';

}


    $hash = md5( rand(0,1000) ); // Generate random 32 character hash and assign it to a local variable.
    // Example output: f4552671f8909587cf485ea990207f3b

[b]$emailCheck = mysql_query("SELECT email FROM users WHERE email = '".$email."'");
if (mysql_num_rows($emailCheck) > 0) {
       echo "already submitted";
}

else
{[/b]

 
        // We have a match, activate the account
             mysql_query("INSERT INTO users (username, password, email, hash) VALUES(
    '". mysql_escape_string($name) ."',
    '". mysql_escape_string(md5($password)) ."',
    '". mysql_escape_string($email) ."',
    '". mysql_escape_string($hash) ."') ") or die(mysql_error());


Thanks in advance,

I am making a secure registration for my website and looking for a function that will verify with a user inputted date exists.

From my registration html form I am putting a month, day and year , each inputted separately into a single variable:
Code: [Select]
$bday = $year . "-" . $month . "-" . $day;
My birthday input looks like:

Code: [Select]
<div class=\"Container FormBoxLeft\">
  <b>Birthdate:</b>
</div>
<div class=\"Container FormBoxRight\">
  <select name=\"month\"><option value=\"\">-Month-</option>
  <option value=\"01\">January</option>
  <option value=\"02\">February</option>
  <option value=\"03\">March</option>
  <option value=\"04\">April</option>
  <option value=\"05\">May</option>
  <option value=\"06\">June</option>
  <option value=\"07\">July</option>
  <option value=\"08\">August</option>
  <option value=\"09\">September</option>
  <option value=\"10\">October</option>
  <option value=\"11\">November</option>
  <option value=\"12\">December</option>
  </select>&nbsp;
<select name=\"day\">
<option value=\"\"> -Day-</option>';
//Print 31 Days
";
    for ($x=1; $x<=31; $x++) {
        echo "<option value='".$x."'"; if(isset($_POST['submit']) && $day == $x) { echo " selected"; } echo ">".$x."</option>\n";
    }
echo "</select>&nbsp;
  <input name=\"year\" size=\"2\" maxlength=\"4\" type=\"text\">

So.. What I am asking is.. is there a secure way to check if the date the user inputted exists, or is there a better way to make the form more secure from that part.  Upon finding the users birthdate I am also wanting to check if the user is a certain age.

I'm working with a registration/login system from a tutorial. It's got email validation to make sure it does not exist but I'm struggling to add the same to the username field:

I've tried adding this after the email verification:

Code: [Select]
// Make sure the user is available:
        $query_verify_user = "SELECT * FROM members  WHERE Username ='$name'";
        $result_verify_user = mysqli_query($dbc, $query_verify_user);
        if (!$result_verify_user) {
            echo ' Database Error Occured ';
        }
}
    if (mysqli_num_rows($result_verify_user) == 0) { // IF no previous user is using this user .
But that just returns me with:

It works to stop username/email duplication but now returns:

Query Failed You could not be registered due to a system error. We apologize for any inconvenience.

Not sure where I'm going wrong tbh.

Hi all

I am trying to write a piece of code that checks to see if an item is in the SQL database and updates the quantity if it is, or adds it as a new line if it isn't. Here's my code:

Code: [Select]

if (isset($_GET['add'])) {

$id = $_GET['id'];
$qty = $_GET['qty'];

$date = date ('D M j G:i:s');

$sql_products = mysql_query("SELECT * FROM `items` WHERE `id` = '".$id."'");
$result_products = mysql_fetch_array($sql_products);
$product_title = $result_products['title'];
$product_price = $result_products['price'];

$sql_inbasket = mysql_query("SELECT * FROM `store_basket` WHERE `id` = '".$id."' AND sessionid = '".$sessionid."'");
$isiteminbasket = mysql_num_rows($sql_inbasket);

if ($isiteminbasket == 0) {

mysql_query ("INSERT INTO `store_basket` SET sessionid = '".$sessionid."', productid = '".$id."', item = '".$product_title."', qty = '".$qty."', price = '".$product_price."', date = '".$date."'");

header("Location: basket.php");
}

else {

mysql_query("UPDATE `store_basket` SET qty = qty + 1 WHERE id = '".$id."' AND sessionid = '".$sessionid."'") ;

header("Location: basket.php");
}

}


Every time I try and add the same item to the basket, it adds as a new line instead of updating the existing line.

Many thanks for your help!

Hi,

I want to make a query and check if data  exists already on my
is_availble table on calendar db tomake it unavailble .
I have 16 checkboxs.

I have this code for first one. And I did it for second one alse, although
data dosen't exist  on db, but it makes it also unvailble!

Here you can see my php code:

PHP Code:
Code: [Select]
<?php
mysql_select_db("calendar", $con);

$result2 = mysql_query("SELECT * FROM is_availble WHERE datetime=$v_datetime ");
//---------------------------------- choeckbox 1(bookable time 1)------------------------\\


echo"<div  class='box'>
<div class='boxbut'>";
if($result2)  {
echo" Booked ";

I am trying to compare an array containing required questions to an array holding survey responses.

When a user submits a survey, I take the $_POST array and write the values to a new array called $surveyResponseArray.

How can I determine if $surveyResponseArray exists?

Hi,
I am trying to update the status of the record. I don't want to insert the record if not exists. I just want to know the update is success or not.

I tried using affected_rows but it returns 0 if the existing status is same as the new status or if no record exists.

Please help.
