PHP - Display Certain Number Of Database Entries (random)

As above,

I have a lottery style site that picks a random number between 1-8 but my users complain for some reason that this is not enough.

So i was told to look into using fopen and random.org to generate a random number.

Anyone have experience of this and perhaps a code snippet for me to look at and possibly use?

help will be appreciated.

My php and MySQL scripting works perfectly,
but when someone enters data into the php form, using an iPad with Safari browser,
all number entries are inserted into the database table incorrectly.
It is still a number entry but the number differs substantially from the original input.

Note: All other entries, where the individual selects something from a drop-down list and date selecter works perfectly from the same form.

Please help me here, since at least 70% of my employees use iPads, thus I need to find a cure for this problem ASAP.

Thanks in advance for any help offered.

I need to display a number(the number is retrieved from the db) in the form input field such that only the last 4 digits is visbile, the remaining can be masked as * or X or whatever is applicable.

I know the last 4 can be obtained as follows:

    Code: [Select]
$number=substr($number,-4,4);
 
But when i hit the submit button the form validates the input field and checks if the number is a valid number of a specific format.
Therefore when I click on the submit button then I should still be able to unmask the masked numbers or do something similar that would help me validate the whole number.

  Code: [Select]
  <input type="text" name="no" value="<?php if(!empty($number)){ echo $number;} ?>">

Hello...
I have a .txt database with ~100 records.  I only want to show the 15 records that are at the top (referring to reading order of the file).
Here is my php code to display the records.
http://www.flcbranson.org/mobile.php?content=mobile-freedownloads.php if you want to see the results of the code, below.
Code: [Select]
<?php
$index_file = 'services/series/Index-Date.txt';
$fd = fopen($index_file, 'r');
if ($fd) {
        while (!feof ($fd)) {
                $seriestitle = trim(fgets($fd, 1024)); // Series Title
                if(feof ($fd))
                break;
                $seriessubtitle = trim(fgets($fd, 1024)); // Series subtitle
                $seriesinfo  = trim(fgets($fd, 1024)); // Series Info (Church name)
                $serieslocation = trim(fgets($fd, 1024)); // City, State
                $seriesindex = trim(fgets($fd, 1024)); // Series index file
                $seriesstatus = trim(fgets($fd, 1024)); //Online Only?
                $divider     = trim(fgets($fd, 1024)); // Divider
                $seriestitle2 = $seriestitle;
                $seriestitle3 = str_replace("'", "%27", $seriestitle); // Kind of makes the alt= below work "God's Will" ends up being "God%27s Will" but without is "God"
                if(strstr($seriestitle,"<")) {
                        $seriestitle2 = strip_tags($seriestitle);
                }
                $seriestitle2 = urlencode($seriestitle2);
                if(file_exists("images/ProductCovers/".substr($seriesindex,0,-4).".jpg")) {
                        echo "<img src='images/ProductCovers/".substr($seriesindex,0,-4).".jpg' width='115' height='150' border='0' alt='".substr($seriestitle3,7)."'><br />";
                }
        }
        fclose ($fd);
}
?>
I'm assuming that "for" would do the trick, but when I tried I got 10 copies of every record.
Hehehe...
I'm guessing that it's a quick fix.
Thanks...

Hello,

For starters I'm not sure if what I want to do is possible, but if it is I would like your input. I have a script that will show a number of fields to fill out in a second form based on the number the user puts into the first from. the problem is that only the last one saves into the database and not all of them.

Code: [Select]
<form auction="index.php" method="post">
System Name: <input type="text" name="systemname">
Number of E-sites: <input type="text" name="events">
Number of Sigs: <input type="text" name="sigs"><br>
<input type="reset" name="reset" value="Reset">
<input type="submit" name="start" value="Start">
</form>
<form auction="index.php" method="post">
<?php
$events = $_POST['events'];
$system = $POST['systemname'];

if (isset($_POST['start'])) {
$num = $_POST['sigs'];
$i = 0;
While ($i < $num)
{
echo "Sig ID: <input type=text name=sigid>";
echo "Type: <input type=text name=type>";
echo "Name: <input type=text name=name>";
echo "Notes: <input type=text name=notes>";
echo "<br>";
$i++;
}
}
?>
<input type="submit" name="enter" value="Enter">
</form>
<?php
$sigid = $_POST['sigid'];
$type = $_POST['type'];
$name = $_POST['name'];
$notes = $_POST['notes'];
mysql_connect('xt', 'x', 'x');
mysql_select_db('wormhole');
if (isset($_POST['enter'])) {

$query = "INSERT INTO sites VALUES ('$system','$events','$sigid','$type','$name','$notes')";
mysql_query($query);

}
?>
How do I get it so all the data saves, lets say that $num = 5, I want all 5 to save not just the last one.

I am quite new so I am sure this is an easy fix for some of the experts around here.

I am using the canned script below to add urls to the database as text.  The problem is if you update one of the form text boxes it loads all the urls into the database again resulting in a lot of duplicates.

My question is, How do I get the form to only post the new changes and not re-post the existing urls?


<?php
session_start();

   if(isset($_SESSION['userSession']) && !empty($_SESSION['userSession']))
   {
        include_once("dbc.php");

        if($_POST)
        {
            $c = 0;
            
            $errMssg = "";

            for($i=0;$i<count($_POST['url']);$i++)
            {
                if($_POST['url'][$i]=="")
                {
                    $c++;
                }
            }
            if($c==5)
            {
                $errMssg = "Submission error . Please fill at least 1 url.";
            }
            else
            {
                for($j=0;$j<count($_POST['url']);$j++)
                {
                    if(!empty($_POST['url'][$j]))
                    {
                        $sql = mysql_query("INSERT INTO images (id ,url ,user_id)VALUES (NULL , '".$_POST['url'][$j]."',".$_SESSION['userId'].")");    

                     }
                                    
                }
                
            }
        }    

        
        

        $sqlresult = mysql_query("SELECT * FROM images WHERE user_id =".$_SESSION['userId']);
        
        $count = 0;
            
        while($data = mysql_fetch_array($sqlresult))
        {
            $image[$count] = $data['url'];

            $count++;

        }
         
?>

Code: [Select]
$query = mysql_query("SELECT a.*, b.*
         FROM friendlist a
INNER JOIN friendlist b
ON (a.friendemail=b.friendemail)
INNER JOIN users c
ON (b.friendemail = c.EmailAddress)
WHERE a.email = 'asdf@gmail.com'
AND c.Username LIKE '%carol%'
GROUP BY a.id
ORDER BY count(*) DESC");
Code: [Select]
while ($showfriends = mysql_fetch_array($query)) {
     echo $showfriends['Username'];
}
and I would get nothing. It produces the correct number of <div> so i know it's getting through, but it's having trouble displaying the entries?

Is there any other way of getting PHP form data into C# any other way besides calling  

www.downloadHandler.text

I am having issues  bringing all the entries into C# and breaking them all up.  I can do one row fine but multiple rows isn't working.  I keep getting an out range error.

This is my PHP echo

echo $row['userName']. '|' .$row['level']. '|' .$row['points']. '|' .$row['killRate']. '/';

And this is my C# code

                string nothing = "Not Placed";
                string Data_string = www.downloadHandler.text;
                string[] DataArray;
                DataArray = Data_string.Split('/');

                int numberOfEntries = DataArray.Length;
                Debug.Log(numberOfEntries);

                if (DataArray[0] == null || numberOfEntries == 1)
                {
                    DataArray[0] = nothing;
                    Debug.Log("Data Array [0] isn't there");
                    High_Points_1.text = DataArray[0];

                }
                else

                    //Debug.Log(DataArray.Length);
                }
                if (DataArray[1] == null || numberOfEntries == 2)

I have two entries in the database.  But when I debugged the number int he array I get 3 strings.

I want to show the top five entries in the database.

I have an issue with some code I have.  All the code works correctly apart from when submit is clicked not only does it update a the current club but it creates a blank entry in the database!  I cant see whats wrong.  Here is the code.........



//gets
$validation = $_GET['new_club'];
//Querys
    $qGetClub = "SELECT * FROM clubs WHERE validationID = '$validation'"; 
$rGetClub = mysql_query($qGetClub);
$Club = mysql_fetch_array($rGetClub);
//Query for category by name
$qGetCat = "SELECT * FROM club_category WHERE catID = ".$Club['cat']."";
$rGetCat = mysql_query($qGetCat);
$CatName = mysql_fetch_array($rGetCat);
//query for related sub categorys.
$qGetSub = "SELECT * FROM sub_categorys WHERE catID =".$Club['cat']."";
$rSubCat = mysql_query($qGetSub);

$newg = mysql_real_escape_string($newg);     
//if an item other than none from the list is selected then update the club with an ID relating to the group it belongs to
if ($otherg !=='None') { $groupsq = mysql_query("UPDATE `clubs` SET groupID ='$otherg' WHERE validationID ='$validation'") or die (mysql_error()); }
// If none is selected then $newg must have a value so create a new group in the groups table and then on the next page I will add the group in the club table 
else {

}   }

if ($NewSubCat !="") { mail("mail","New Sub Category Request","Dear Ring Master,
\n\nThe club in the name of $name with a validation code of $validationID would like a new sub category called $new_cat\n\n  
\nTeam Arena\n\n\n\n"); }

$url = "/members/create/create_clubp3.php?new_club=$validation";  
header("Location: $url");     
}

For some reason my for loop only seems to be storing some data in my fields, most of the time the data is not true but simply duplicating one of the entries. So instead of having a string of 1,2,3,4 for instance it would store all of them as 4. The entires are selected using fields in a multiple select box, in theory of someone choses 10 unique entries from the "Systems" category all 10 should be made into rows in the MySQL table.

Any idea why this is happening?

The form,

if ($type == "games") {

echo "<tr><td>".$name."</td><td><select name='".$name."_".$i."'[] multiple='multiple'><option value='' selected>--------</option>";

$sqla = mysql_query("SELECT * FROM ".$pre."games ORDER BY `name` ASC") or die(mysql_error());

while($row2a = mysql_fetch_array($sqla)) {
$system = mysql_fetch_array(mysql_query("SELECT * FROM ".$pre."systems WHERE id = '".$row2a[system]."'"));
echo "<option value='".$row2a[id]."'>".$row2a[name]." - ".$system[name]."</option>";
}
echo "</select></td></tr>";
}

if ($type == "system") {
echo "<tr><td>".$name."</td><td><select name='".$name."_".$i."'[] multiple='multiple'><option value='' selected>--------</option>";

$sqlb = mysql_query("SELECT * FROM ".$pre."systems ORDER BY `name` ASC") or die(mysql_error());
while($row2b = mysql_fetch_array($sqlb)) {
echo "<option value='".$row2b[id]."'>".$row2b[name]."</option>";
}
echo "</select></td></tr>";
}

The PHP code,

while($row = mysql_fetch_array($query)) {
$name = "$row[name]";

for ($i = 0; $i < count($_POST["systems_$i"]); $i++) {
   mysql_query("INSERT INTO ".$pre."fielddata VALUES (null, 'systems', '".$_POST["systems_$i"]."', '".$fetch[0]."', 'content')");
}

for ($i = 0; $i < count($_POST["games_$i"]); $i++) {
   mysql_query("INSERT INTO ".$pre."fielddata VALUES (null, 'games', '".$_POST["games_$i"]."', '".$fetch[0]."', 'content')");
}

Hi,
I want to be able to generate visitor statistics for a blog I'm creating. I'm going to be collecting numerous pieces of data when a post is viewed, including a time stamp of the visit.

I need to be able to select timestamps that were within the current day, the previous day, the day before that ect.. So that I can generate the statistics.
Show it for the current week (current day and 6 previous days).

So it would be the entries where the timestamp was made on the days: 11/1, 10/1, 9/1, 8/1, 7/1, 6/1, 5/1. For example.

Not quite sure how I could do this.

Thanks.

I coded the following but some parts are not working (the "curveball" mentioned at the end).
How would YOU do this?

I have a page (A) displaying a form with a textarea field using a WYSIWYG interface.
The user will enter a list of unordered items and upon submit the string will look something like this:

This is my list of food items:
 <ul>
  <li> Lettuce </li>
  <li> Tomatoes </li>
  <li> Eggs </li>
 <ul>




Upon submit, I need to give each list item an unique id and store this id along with the text next to it in a separate table:

List_item_id   List_item_text  List_item_state
food_1             Lettuce
food_2             Tomatoes
food_3             Eggs





The user will then land in another page with a form displaying the list. The text is now in the page itself and not in a textarea.
Instead of the bullets a dropdown list appears, and the user can select "buy" or "sell" for each list item. 
This page (B) looks something like this:

<form>
This is my list of food items:
  <br><select name="food_1">
   <option value="buy">Buy</option>
   <option value="sell">Sell</option>
  </select>
  Lettuce

  <br><select name="food_2">
   <option value="buy">Buy</option>
   <option value="sell">Sell</option>
  </select>
  Tomatoes

  <br><select name="food_2">
   <option value="buy">Buy</option>
   <option value="sell">Sell</option>
  </select>
  Eggs

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




When the user hits "submit" the table with the list items will be updated with the values selected in the dropdown list:

List_item_id   List_item_text  List_item_state
food_1             Lettuce        Buy
food_2             Tomatoes       Buy
food_3             Eggs           Sell



The next time the user goes to Page B the list will remember the states.


Here's the curveball: At any point the user may click on "EDIT LIST" on Page B so they may add more items (at the begining, middle or end of the string). On edit mode the list items should appear as bullets again inside the WYSIWYG interface.

Keep in mind that some of the text in the string may not be a list item (ie, "this is my list of food...")

Hello. Many thanks for your help.

I am writing a PHP/MySQL dating-site and have hit a programming impass.

I have a database full of members and a search form consisting of checkboxes.

So to search, a member ticks say...gender: female; age: 21,22,23,24,25,26; height: 5'4",5'5",5'6",5'7"; county: cornwall,devon,somerset

How can a run a check on the database selecting all entries that fall into the selected criteria. For example a 23 year old female of 5'5" living in Cornwall and a 26 year old female of 5'4" living in Somerset?

The key index of my database is 'id' and the fields a age,height,county
The names of the form checkboxes a
Gender: male, female; Age: 21,22,23,24 etc; Height: 5_4,5_5,5_6 etc; county: cornwall,devon etc

Im trying to create a website where users login, and then when they add a new entry to the database there name is put as the author. This is how my tables are set up. One table is named job and has the columns id, jobtext, jobdate, and authorid. Another table is called author. This table contains the columns id, username, password, and name. Authorid from the job table matches with id from the author table. When a user logins in this code is used to register the name...session_start();
$_SESSION['myusername'] = $_POST['myusername'];
$_SESSION['mypassword'] = $_POST['mypassword'];
header("location: index.php");
}
else {
echo "Wrong Username or Password";
}

This is the form users use to add a new entry...
if (isset($_GET['add']))
{
$pagetitle = 'New Job';
$action = 'addform';
$text = '';
$authorid = '';

$result = mysqli_query($link, $sql);
if (!$result)

exit();
}
