PHP - Not Adding Data To Db

I have two tables 'book' and 'category'. They look like the following in phpmyadmin;   book   id   title                    author      category     isbn
---- -------                 ----------   ----------  ------- 
1    Treasure Chest     Jim Jones     1           14252637 2    Pirates Boat         Sue Smith    2           88447737 3    Adventure Land   Harry Jo      3           01918273 4    Winter Week       Sam Dill      3           00999337 5    The Twite           Roald Dahl   Fiction   87873366   category   id       cat_name   
----     -------         
1        Horror 2        Kids 3        Fiction 4        Science   Users have the option of adding books into the library via an online form, or via a Google Booka api method (user enters isbn, searches, is presented with book info and then clicks 'add to library', done.). This is handled via ajax.   The online form works fine, and successfully adds the book info. However my problem is with the Google Books method, it successfully adds the data to the db however the category column is in text format (i.e 'Juvenile Science' or 'Scary Fiction') as opposed to the manual form which adds categories as 1, 2 or 3 (1 =Horror, 2 = Kids, 3 = Fiction).   Is there any way I can add the Google Book category data to my table and convert it to an integer or similar? Not sure what I need to do. Suggestions appreciated! Should I add the Google entries to another table (i.e googleCategory)?   My HTML only outputs the numbered category entries and ignored the text format entries.   my php

$sql = "SELECT b.id, b.title, b.author, b.isbn, b.publicationYear,
        c.cat_name
        FROM book AS b
        INNER JOIN category AS c ON b.category = c.id
        WHERE status != 'Archive' ORDER BY id DESC LIMIT $startrow, 15 ";


$res = $conn->query($sql) or trigger_error($conn->error."[$sql]");


while($row = $res->fetch_array()) {


    echo '<tbody>';
    echo '<tr>';
    echo '<td>' . $row['id'] . '</td>';
    echo '<td>' . $row['title'] . '</td>';
    echo '<td>' . $row['author'] . '</td>';
    echo '<td>' . $row['cat_name'] . '</td>';
    echo '<td>' . $row['isbn'] . '</td>';
    echo '<td>' . $row['publicationYear'] . '</td>';
    echo '</tr>';
    echo '</tbody>';
};

Apologies if this is all a bit confusing I am very new to php and mysql. Thanks,   J

Hi I have currently written some code which uses of the Twitter API and extracts the information required to display my most current tweet on my website. This is all working perfectly but at the minute it is only displaying one tweet and I would like it to display as many as the variable $limit is set to.

I have tried numerous count with while loops but just cannot seem to get my head around the logic of it.

Here is the code im currently using which displays one tweet.


            <?php

$username = "my_twitter_username";
$limit = "2";
$twitter_url = "http://twitter.com/statuses/user_timeline/$username.xml?count=$limit";

$buffer = file_get_contents($twitter_url);
$xml = new SimpleXMLElement($buffer);

$status_item = $xml -> status;
$status_id = $xml -> status -> id;
$user_item = $xml -> status -> user;
$user_id = $xml -> status -> user -> screen_name;
$description =  $status_item -> text;
$status_time =  $status_item -> created_at;
$status_img = $user_item -> profile_image_url;

$description = preg_replace("#(^|[\n ])([\w]+?://[\w]+[^ \"\n\r\t< ]*)#", "\\1<a href=\"\\2\" target=\"_blank\">\\2</a>", $description);
        $description = preg_replace("#(^|[\n ])((www|ftp)\.[^ \"\t\n\r< ]*)#", "\\1<a href=\"http://\\2\" target=\"_blank\">\\2</a>", $description);
        $description = preg_replace("/@(\w+)/", "<a href=\"http://www.twitter.com/\\1\" target=\"_blank\">@\\1</a>", $description);
        $description = preg_replace("/#(\w+)/", "<a href=\"http://search.twitter.com/search?q=%23\\1\" target=\"_blank\">#\\1</a>", $description);

echo "
<div class='tweet-wrapper'>
<div class='tweet-img'>
<a href='http://www.twitter.com/la__academia' target='_BLANK'><img src='$status_img' alt='La Academia Twitter' style='width:30px height:30px;' /></a>

I'm trying to add some data into my database through a form interface, but this form submits even when the page loads. This means the form submits regardless of the validation I have set in place, so every time the page is loaded, the database receives empty fields. Could you guys please help me with my problem?

I have the really long IF statements in there so that it enters the correct EnrID and EnrVenID into the database, to make sure it fills out all fields. I am using Microsoft access for my database.

The problem is that it will only fill in the athlete's name and country, and not his/her enrollment information (what medal they got, their enr ID, what year it was taken place, etc.




The problem with my login system is that I want the user to login with a username and password if they wish to be an admin, but the login system doesn't work. the variables aren't passed through the system for some reason, even though it worked a week ago,  but now it doesn't.
The code is Code: [Select]
if(isset($_POST['username'])){
$username= $_POST['username'] ;
}
if(isset($_POST['password'])){
$password= $_POST['password'] ;
}

$username = null ;
$password = null ;
Thanks for any help

Hi,

I'm making a website that uses data stored in SQL.

One of my pages allows the user to enter a new product into a product table. I was wondering if somebody could help me with some validation or Query that will not allow the user to enter a product name that already exists in the table?

Code: [Select]

$nameNew = $_POST['new];
$nameID = $_POST['newID];
$namePrice = $_POST['newPrice];

INSERT INTO products
VALUES ($nameNew, $newID, $newPrice)

$describeQuery = "SELECT ID, Name, Price FROM Products";


$results = sqlsrv_query($conn, $describeQuery);

echo '<table border="1" BORDERCOLOR=Black>';
echo '<tr><th bgcolor = "LightBlue">Name</th><th bgcolor = "LightBlue" >ID</th> <th bgcolor = "LightBlue" >Price</th></tr>';


while($row = sqlsrv_fetch_array($results, SQLSRV_FETCH_ASSOC))
  {   
    echo '<tr>';
echo '<td >' .$row['Name'].'</td>';
echo '<td>' .$row['ID'].'</td>';
echo '<td>' .$row['Price'].'</td>';

echo '</tr>';
}

echo '</table>';
sqlsrv_close($conn);


   
Thanks

So i have an event page where it will show the next 3 events, then i need logged in users to click either of two buttons to say there attending or not attending.

i have the below code showing events, and the <form> and the submit and both buttons, but if i submit 1 button on event ID: 1 it inserts data into the database but for event ID: 2, and if i click the button on event ID :2 it also puts it into database with eventid:2

so no matter which event i click it seems to submit data with the latest event ID shown on page, and not for "each" event seperatly.

i have moved the submit query everywhere around and still same results or duplicate results if its in the loop.

i assume its looping the submit and only submitting the latests event ID.

 

<?php
if ($result = $con->query("SELECT * FROM events ORDER BY id ASC LIMIT 3")) {
if ($result->num_rows > 0) {
while ($row = $result->fetch_object()) {
$event_id = $row->id;
// set up table and echo data!
echo "<table border='1' cellpadding='2' width='50%'>";
echo "<tr><td>";
echo "<p><img src='images/raid_banners/" . $row->bannerimg . "'>" . $row->name . " (iLvl: " . $row->itemlevel . ")</p>";
echo "<p>Event Starts: " . $row->datestart . " - " . $row->timestart . "</p>";
echo "<p>Event Ends: " . $row->dateend . " - " . $row->timeend . "</p>";
echo "<p>Raid Lead: " . $row->raidlead . "</p>";
echo "<form action='' name='$event_id' method='post'>";
// Process and populate SELECT form element
echo "<select name=\"charname\">";
$sql = mysqli_query($con, "SELECT * FROM characters WHERE userid = $userid");
while ($row = $sql->fetch_assoc()){ echo "<option value=\"{$row['id']}\">{$row['charname']}</option>"; }
echo "</select>";
echo "<input type='hidden' name='raidid' value ='$event_id'>";
echo "<input type='hidden' name='action' value='submit' />";
echo "<input type=\"submit\" name=\"submit\" value=\"going\">";
echo "<input type=\"submit\" name=\"submit\" value=\"notgoing\">";
echo "</form></td></tr></table><br><br>"; 
 } 
 if(isset($_POST['action'])){
$charid = $_POST['charname'];
$submit = $_POST['submit'];
// Submit the data from dropdown in the form
mysqli_query($con,"INSERT INTO eventsignup (eventid, charid, userid, status) VALUES ('$event_id', '$charid', '$userid', '$submit')");  } 
}
else { echo "No results to display!"; } }
else { echo "Error: " . $con->error; }
$con->close();
?>

any help would be awesome. im tearing my hair out here.

Greetings,

What I'm trying to do is have users upload their event information into a database which would include a flyer.  I don't want the image file to go into the database (other than the filename) rather I'd like it to be dropped into a directory.  In the same script I'd like to dynamically generate a thumbnail.  I have the two scripts and separately they work fine, but I can't get them to work together.

I'm guessing the conflict because the thumbnail script is using $_POST and the mysql script is using $_SESSION.  If so how can I modify them to both use $_SESSION?

The thumbnail script is goes from line 1 - 146 and the mysql portion is the rest.

Using curl_multi, I have loaded up 3 url's and then printed the array.

1) How can I also set a timestamp on output to let me know when each url was run?

2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"? Code

<?php

Am new here - looks like a great foru!

I would sincerely appreciate any help anyone can give me. I have been
trying to solve my problem for hours and I am not having any luck, so I
thought I would post and see if anyone can help. I am very stuck and am
not making much progress on this project, and I am certain the answer is
very simple.

I am constructing a form to collect data for a specialized purpose. 

The form and program actually work for its intended function, but I am
trying to enhance the user experience by preventing customers from
having to reenter all of their data should there be a problem with any
of the data submitted.

I have been able to do that with the contact form portion, but what I am
having trouble with is the portion which has as many as 400 possible
entries.

So, in a nutshell, if the customers contact data is incomplete or in
error, the form will ask them to return to the page and correct things.
The previous data entered has been saved in the session and the input
value will equal the previous entry.

i.e.

<tr>
  <td align="right" class="infoBox"><?php echo ENTRY_EMAIL_ADDRESS; ?></td>
  <td align=left><?php echo "<input type=text name='cemail' value=\"$cemail\" size=35 maxlength=35>" ?></td>
</tr>

Works perfectly, all well and good there.

On the other 400 more or less entries, I am having a difficult time
tweaking the string concatenation to work to achieve similar results.

There are 4 columns each with $points entries asking for a dimension in
either feet or inches. 

The <input name=>  is one of ptaf,ptai,ptbf,ptbi, appended programatically with the corresponding
row number or data point.  i.e. "ptaf1", "ptai1", etc...  This is produced by the example
below and works perfectly also.

<?php {
$points=100;
$i=1;
while ($i <= $points)
{echo '
  <tr><td align="center" width="6"><b>  ' .$i . '</b></td>
     <td align="right" NOWRAP>A' .$i . ' (ft) <input type="text" name="ptaf'.$i.'" size=4 maxlength=3> </td>
      <td align="right" NOWRAP>A' .$i . ' (in) <input type="text" name="ptai'.$i.'" size=4 maxlength=4> </td>
     <td align="right" NOWRAP>B' .$i . ' (ft) <input type="text" name="ptbf'.$i.'" size=4 maxlength=3> </td>
      <td align="right" NOWRAP>B' .$i . ' (in) <input type="text" name="ptbi'.$i.'" size=4 maxlength=4> </td>

';

     $i++;
}   
}
?>


I am trying to add <input value=$ptai.$i> for each field but as I mentioned I
am not having any luck.  It seems as if I have tried every combination
imagineable, but still no luck. My head is spinning!

The closest I seem to have gotten was with this:

<td align="right" NOWRAP>A' .$i . ' (ft) <input type="text" size=6 maxlength=3 name="ptaf'.$i.'"  value="' . "$ptaf" . $i . '" ></td>

But line 17 for example returns this:

<input type="text" value="17" name="ptaf17" maxlength="3" size="6">

To recap, I am trying to have the value set to whatever the customer may
have entered previously.

Again, I would most appreciate any help anyone can give me. If you need
 clarification on anything please let me know.

Thanks

AJ

 

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?
Here is part of the HTML code:

<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>';
    }
    ?>

P.S. Please know that I have purposely omitted the connection part and the methods in the class that are used in this code to keep the spot of the problem as clean as possible. If you need me to rephrase the question, please ask.

Thank you.

Hi, after banging my head against the wall for a while thinking this would be a simple task, I'm discovering that this is more complicated than I thought.

Basically what I have is a link table linking together source_id and subject_id.   For each subject there are multiple sources associated with each.

I had created a basic listing of sources by subject... no problem.   I now need a way of having a form to create an ordered list in a user-specified way.  In other words, I can currently order by id or alphabetically (subject name lives on a different table), but I need the option of choosing the order in which they display.  I added another row to this table called order_by.  No problem again, and I can manage all of this in the database, however I want to create a basic form where I can view sources by subject and then enter a number that I can use for sorting.

I started off looping through each of the entries and the database (with a where), and creating a foreach like so (with the subject_id being grabbed via GET from the URL on a previous script)
Code: [Select]
while($row = mysqli_fetch_array($rs)) {


//update row order
if (isset($_POST['submit']))  {

//get variables, and assign order

$subject_id = $_GET['subject_id'];
$order_by = $_POST['order_by'];
$source_id = $row['source_id'];


//echo 'Order by entered as ' . $order_by . '<br />';

foreach ($_POST['order_by'] as $order_by) {

$qorder = "UPDATE source_subject set order_by = '$order_by'
WHERE source_id = '$source_id'
AND subject_id = '$subject_id'";

mysqli_query($dbc, $qorder)
or die ('could not insert order');

// echo $subject_id . ', ' . $order_by . ', ' . $source_id;
// echo '<br />';
} 
}
else {
$subject_id = $_GET['subject_id'];
$order_by = $row['order_by'];
$source_id = $row['source_id'];

}

And have the line in the form like so:
Code: [Select]
echo '<input type="text" id="order_by" name="order_by[]" size="1" value="'. $order_by .'"/>

(yes I know I didn't escape the input field... it's all stored in an htaccess protected directory;  I will clean it up later once I get it to work)

This, of course, results in every source_id getting the same "order_by" no matter what I put into each field.

I'm thinking that I need to do some sort of foreach where I go through foreach source_id and have it update the "order_by" field for each one, but I must admit I'm not sure how to go about this (the flaws of being self-taught I suppose;  I don't have anyone to go to on this).

I'm hoping someone here can help?

Thanks a ton in advance

Say there is a complex opt in process where people start to enter their data but certain questions stop them where they close out of the page. They already entered their data and I feel there is a way to grab it and post it to mysql even though they do not click submit.   How would this be done?   A super simple example (proof of concept) or a link to a tutorial would be very useful.

I have two tables.

Table Name:Users

Fields:

User_name
user_email
user_level
pwd


2.Reference

Fields:

refid
username
origin
destination

user_name in the users table and the username field in reference fields are common fields.



There is user order form.whenever an user places an order, refid field in reference table will be updated.So the user will be
provided with an refid

Steps:

1.User needs to log in with a valid user id and pwd
2.Once logged in, there will be search, where the user will input the refid which has been provided to him during the time of order placement.
3.Now User is able to view all the details for any refid
3.Up to this we have completed.

Query:

Now we need to retrieve the details based on the user logged in.

For eg: user 'USER A' has been provided with the referenceid '1234' during the time of order placement
user 'USER B' has been provided with the referenceid '2468' during the time of order placement

When the userA login and enter the refid as '2468' he should not get any details.He should get details only for the reference ids which is assigned to him.



<?php


session_start();

if (!$_SESSION["user_name"])


      

{
        // User not logged in, redirect to login page
        Header("Location: login.php");

if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("login", $con);
$user_name = $_POST['user_name'];
$refid = $_POST['refid'];
$query = "SELECT * from reference,users WHERE reference.username=users.user_name AND reference.refid='$refid' AND ";

  {
  echo $row['refid'];
  echo $row['origin'];
  echo $row['dest'];
  echo $row['date'];
  echo $row['exdate'];
  echo $row['username'];
  }
echo "<p><a href=\"logout.php\">Click here to logout!</a></p>";
?>

 <html>
<form method="post" action="final.php">
Ref Id:<input type="text" name="refid">
<input type="submit" value="submit" name="submit">
</html> 

This could be PHP or MySql so putting it in PHP forum for now...
I have code below (last code listed) which processes a dynamically created Form which could have anywhere from 0 to 6 fields.  So I clean all fields whether they were posted or not and then I update the mySQL table.

The problem with this code below is that if, say, $cextra was not posted (i.e. it wasnt on the dynamically created form), then this code would enter a blank into the table for $cextra (i.e. if there was already a value in the table for $cextra, it gets overwritten, which is bad).

What is the best way to handle this?  I'm thinking i have to break my SQL query into a bunch of if/else statements like this...

Code: [Select]
$sql = "UPDATE cluesanswers SET ";
if (isset($_POST['ctext'])){
echo "ctext='$ctext',";
} else {
//do nothing
}
and so on 5 more times....

That seems horribly hackish/inefficient.  Is there a better way?

Code: [Select]
if (isset($_POST['hidden']) && $_POST['hidden'] == "edit") {

$cimage=trim(mysql_prep($_POST['cimage']));
$ctext=trim(mysql_prep($_POST['ctext']));
$cextra=trim(mysql_prep($_POST['cextra']));
$atext=trim(mysql_prep($_POST['atext']));
$aextra=trim(mysql_prep($_POST['aextra']));
$aimage=trim(mysql_prep($_POST['aimage']));


//update the answer edits
$sql = "UPDATE cluesanswers SET ctext='$ctext', cextra='$cextra', cimage='$cimage', atext='$atext', aextra='$aextra', aimage='$aimage'";
$result = mysql_query($sql, $connection);
if (!$result) {
die("Database query failed: " . mysql_error());
} else {
}

Here's the code that deals with the client side:

<?php 
session_start(); 
if(!isset($_SESSION['Logged_in'])){
header("Location: /page.php?page=login");
}
?>
<!DOCTYPE Html>
<html>
<head>
<!--Connections made and head included-->
<?php require_once("../INC/head.php"); ?>
<?php require_once("../Scripts/DB/connect.php"); ?>
<!--Asynchronously Return User Names-->
<script>
$(document).ready(function(){
function search(){
        var textboxvalue = $('input[name=search]').val();
        $.ajax(
        {
            type: "GET",
            url: 'search.php',
            data: {Search: textboxvalue},
            success: function(result)
            {
                $("#results").html(result);
            }
        });
};​
</script>
</head>
<body>
<div id="header-wrapper">
<?php include_once("../INC/nav2.php"); ?>
</div>
<div id="content">
<h1 style="color: red; text-align: center;">Member Directory</h1>
<form onsubmit="search()">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<label for="search">Search for User:</label>
<input type="text" size="70px" id="search" name="search">
</form>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a href="index.php?do=">Show All Users</a>|<a href="index.php?do=ONLINE">Show All Online Users</a>
<div id="results">
<!--Results will be returned HERE!-->
</div>

  search.php 

<?php
//testing if data is sent ok
echo "<h1>Hello</h1><br>" . $_GET['search'];
?>

This is the link I get after sending foo.    http://www.family-li...php?&search=foo   Is that mean it was sent, but I'm not processing it correctly? I'm new to the whole AJAX thing.
