PHP - Help With Php / Mysql Database Update Script

Hi.
I'm trying to use UPDATE to update my datebase.  When I run the code inside mysql phpadmin it works fine.  But when I try and run something similiar from my php page its not updating.
UPDATE user SET password='newpass', verified='0', random='asldk445435' WHERE email='email@email.com'


This is the section that isn't working:

                        // Thank you Page
                        //generate new random number for activation process
                        $randomcode = md5(rand(23456789,987654321));
                        // generate a new random password
                        $newtemppass = createRandomPassword();
                        // encrypes new password
                        $newtemppass = md5(rand(23456789,987654321));
                        $random = $randomcode;
                        $verified = "0";
                        // Setup query to update datebase
                        $query = "UPDATE {$usertable} SET password='$newtemppass', verified='$verified', random='$random' WHERE email='matt@flemingds.com' ";
                        echo "<p>--------------</p>";
                        echo "<p>--------------</p>";
                        echo $newtemppass .' '.'This is your new password';
                        echo "<p>--------------</p>";
                        echo $verified .' '.'You are no longer verfied';
                        echo "<p>--------------</p>";                        
                        echo $random .' '.'New Random Code';
                        echo "<p>--------------</p>";

Hello everyone I need code for this question    would you help me please..?

Hello, I am trying to pick up php again and just exercising my skills. So I have it so that it fills my form with the values of what I want to edit, and when I click the edit button, it doesn't edit any of the information. When I echo out $result, I get a MYSQL query string that has the same values as the table, so its not getting the new values that are edited.


<?php

@mysql_connect('localhost', 'root', '') or die("Could not connect to Mysql Server. " . mysql_error());

@mysql_select_db('tutorials') or die("Could not connect to Database. " . mysql_error());

if(isset($_GET['edit']))

{

$id = $_GET['edit'];

$query = "SELECT `username`, `password` FROM `users` WHERE `id` = '$id'";

$result = mysql_query($query);

$row = mysql_fetch_array($result);

$name = $row['username'];

$password = $row['password'];

}

if(isset($_POST['edit']))

{

$id = $_GET['edit'];

$query = "UPDATE `users` SET `username` = '$name', `password` = '$password' WHERE `id` = '$id'";

$result = mysql_query($query);

echo $query;

if(!$result)

{

echo mysql_error();

}else{

echo 'updated post';

}

}
?>
<form method="POST" action="" >

<input type="text" name="name" value="<?php echo $name; ?>" /> First name <br />

<input type="text" name="password" value="<?php echo $password; ?>" /> Last name <br />

<input type="submit" name="edit" value="edit" />
</form>


I believe it has something to do with the values of $name and $password in the form conflicting with the first if isset and the second if isset.

Thanks for any help possible

$month = $_POST['month'];

Hi there,

I am using this code to send the users email address to the database. That works fine, but i keep getting blank info added to the database. Does anyone know how i can stop this?

<?php
$con = mysql_connect("*","*","*");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("ogs_mailinglist1", $con);

$sql="INSERT INTO mailinglist (email)
VALUES
('$_POST[rec_email]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }

mysql_close($con);
?>



Thanks,

Hi
I don't know exactly what to do to see correct date of birth into my sql database.  I have following code i.e.
$month=$_POST['month'];
$year=$_POST['year'];
$date=$_POST['date'];
$date_value="$month/$date/$year";
echo"YYYY-mm-dd format:$date_value";

and sql insert statement is like this
$sql = "INSERT INTO table_name(fname, lname, gender, add1, add2, city, state, zip, country, email, phone, cellphone, dob, photo1)
VALUES('$fname','$lname','$gender','$add1','$add2','$city','$state','$zip','$country','$email','$phone','$cellphone',
'$date_value','" . $image['name'] . "')";

I don't know what exactly I need to do?  Even though I changed the setting in php ini  to register_globals = On
I would appreciate any kind of help regarding this matter.
Thanks

Hi, this is my first post:) pretty sure i will be posting here in the future. Anyway i am having trouble with a php script which downloads a file from a mysql database.

This php script works for text files and should work for most files from what i understand. When downloading a text file, the whole file is downloaded from the server. When downloading an mp3 file, only 16kb are downloaded and the file does not play. When looking at the data in the database, it displays that the full file is there (correct amount of bytes, so there is nothing wrong with my upload php script). Does anyone have any suggestions as to what I can change to make this work?

Code: [Select]
<?php
if(isset($_GET['id'])) 
{
// if id is set then get the file with the id from database
$link=mysql_connect('localhost', 'root', '');
@mysql_select_db('filemgr') or die ("<p>Could not connect to mysql!</p>");

$id    = $_GET['id'];
$query = "SELECT name, type, size, content " .
         "FROM upload WHERE id = '$id'";

$result = mysql_query($query) or die('Error, query failed');
list($name, $type, $size, $content) =  mysql_fetch_array($result);

header("Content-length: $size");
header("Content-type:$type");
header("Content-Disposition: attachment; filename=$name");
echo $content;

mysql_close($link);
exit;
}
?>

After spending 3 days on internet and struggling with so many different forums , i have found this forum where i believe i will get the solution for my problem.

Friends, I am zero in PHP, but still i have managed to do something to fulfill my requirement.

I am stuck with one thing now..So i need help on....

I am using one html+php form to submit database into mysql.
I created a display of that table through php script on a webpage.
Now i want a datepicker option on that displayed page by which i should able to select the date range and display the data of that date range from my mysql table.
And then take a export of data displayed of selected date range in excel.

This displayed page is login protected, so i want after login the next thing comes in should show a sate selection option which should be fromdate to to date , and then records should displayed from the database and i can take export of those displayed results in excel file.
The code i am using on this page is below which do not have any thing included for excel export and datepicker script, I am pasting the code here and request you to please include the required code in it as required.

Thanks In advance

Hi All,

I've searched long and hard accross the web for an answer to this and finnally given in and requesting help. Here's what i have, i have a database setup and working fine. What i would like to do is for an administrator to be able to update my users details. It may sound odd, why don't you let your users update their own details? Well the administrators are dispatchers if you like, and my users are the 'dispatchees', for want of a better word. So i would like my administrators to be able to dispatch my users with routes and my users be able to see the routes that have been dispatched to them. I've setup a login area and a page that pulls there routes off the database, depending on their login details, i.e. jack will see his routes and jill will see her's independantly. This works by me editing the appropriate columns/rows of my database using phpmyadmin. What i'd like now is for administrators (who are directed to a seperate page, with more controls) to be able to do the same as me (updating the database) but by using a php form/script.

I'd like to be able to select the routes from a second table on the same database if possible, to try and keep everything tidy. So my dispatcher would select Route001 from a drop down list, this would fill in the text fields next to the route field with From To, so my dispatcher would know what route001 actually is from/ too, choose a username (now being driven from my other table) and hit dispatch. My user would login to their area, hit view dispatched routes and it would display Route 001 with the correct information.

The login area was a downloaded script i modified to suit and is called Login-Redirect_v1.31_FULL

Many thanks in advance, hope you can sort of understand what i want

Can anyone post a generic update function to update mysql table.
The manual approach:

update $tablename
set $column1='a', $column2='b'
where $id=$value;

Good morning. I am looking fo some help with an update script to update all rows in a table.

This is what I have for a form and all looks well. form.php

<?php

// run the query and put the results in an array variable called $result 
$result = mysql_query("SELECT * FROM table ORDER BY 'id', 'title', 'text', 'number'"); 


print "<form method='post' action='update.php'> 
<table width='100%' border='0' cellspacing='1' cellpadding='1'><tr> 

<td align='center'><strong>ID</strong></td> 
<td align='center'><strong>Title</strong></td> 
<td align='center'><strong>text</strong></td> 
<td align='center'><strong>Number</strong></td> 
</tr>\n"; 

// start a loop to print all of the courses with their book information 
// the mysql_fetch_array function puts each record into an array. each time it is called, it moves the array counter up until there are no more records left 
while ($Update = mysql_fetch_array($result)) { 


  // start displaying the info; the most important part is to make the name an array (notice bookinfo[$i]) 
  print "<td align='center'><p>{$Update['id']}</p></td>\n"; 
  print "<td align='center'><input type='text' name='title' value='{$Update['title']}' /></td>"; 

  print "<td align='center'><input type='text' size='40' name='text' value='{$Update['text']}' /></td>\n"; 
  print "<td align='center'><input type='text' size='40' name='number' value='{$Update['number']}' /></td>\n"; 
print "</tr>\n"; 
// add 1 to the count, close the loop, close the form, and the mysql connection 

} 
print "<tr> 
<td colspan='4' align='center'><input type='submit' value='submit' />"; 
print "</td> 
</tr> 
</table> 
</td> 
</tr> 
</form> 
</table>"; 

print "</tr>\n";

My question is. How do I update this info into the database with the proper info. ie. Update.php?

Hi i have this upload script which works fine it uploads image to a specified folder and sends the the details to the database.
but now i am trying to instead make a modify script which is Update set so i tried to change insert to update but didnt work can someone help me out please
this my insert image script which works fine but want to change to modify instead
Code: [Select]
<?php
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("upload") or die(mysql_error()) ;

//echo $_FILES["myfile"]["type"];

//myfile is the name of the input area on the form 
$name = $_FILES["image"] ["name"]; // name of the file
$type = $_FILES["image"]["type"]; //type of the file
$size = $_FILES["image"]["size"]; //the size of the file
$temp = $_FILES["image"]["tmp_name"];//temporary file location when click upload it temporary stores on the computer and gives it a temporary name
$error =array(); // this an empty array where you can then call on all of the error messages
$allowed_exts = array('jpg', 'jpeg', 'png', 'gif'); // array with the following extension name values

$appendic_name = "news".$name;//this append the word [news] before the name so the image would be news[nameofimage].gif

// substr counts the number of carachters and then you the specify how how many you letters you want to cut off from the beginning of the word example drivers.jpg it would cut off dri, and would display vers.jpg
//echo $extension = substr($name, 3);

//using both substr and strpos, strpos it will delete anything before the dot in this case it finds the dot on the $name file deletes and + 1 says read after the last letter you delete because you want to display the letters after the dot. if remove the +1 it will display .gif which what we want is just gif
$extension = strtolower(substr($name, strpos ($name, '.') +1));//strlower turn the extension non capital in case extension is capital example JPG will strtolower will make jpg

I'm trying to update my database so that if someone enters an e-mail address that doesn't exist, the program updates the database with the new address. I've tested everything and $result returns the correct data every time (0 or 1) but if the address doesn't exist, nothing gets updated. I know I'm missing something, just not sure what it is...
Code: [Select]
{
$result = mysql_query("
SELECT *
FROM PlayerInfo
WHERE Player_Email = '$playeremail'");

IF($result) {

     IF (mysql_num_rows($result) = 0)
{
//Insert into database: new e-mail address...
}
}
I've also tested the insert into statement and it works, so that's not the issure.  Any help appreciated. Thanks.
