PHP - Need Help Fetching Array Values From Database! Please! :))
I have made an autocomplete form... originally the values were static:
$aUsers = array( "Adams, Egbert", "Altman, Alisha", "Archibald, Janna", ); Now I want the values from a database table DEVICES row name DeviceName: $sql = "SELECT DeviceName FROM DEVICES"; $res = mysql_query($sql); $aUsers = array(); while ($row = mysql_fetch_assoc($res)) { $aUsers[] = $row; } It will not display the values in my autocomplete form when text is entered.... but with static data it will. Im confused! Thank you Similar TutorialsHello there,
I'm really new at PHP and I've been reading several beginner tutorials so please accept my apologies for any stupid questions I may ask along the way.
I've gotten as far as installing XAMPP, set up a database plus PHP form and I'm struggling to figure out how to insert values from an array into my database.
I've learnt the code in one particular way (see beginner tutorials) so I was wondering if you could help me keeping this in mind. I know there'll be a million better ways to do what I'm doing but I fear I will be bamboozled with different code or differently structured code.
Anyway the tutuorials I'm reading don't see to cover how I can insert an array of values into my database, just singular values.
In the attached file, I have 10 rows of 2x text inputs (20 text inputs total). Each row allows the user to enter a CarID and CarTitle. I've commented out the jQuery which validates the inputs so I can build a rudimentary version of this validation with PHP.
I thought that because the line $sql="INSERT INTO carids_cartitles (CarID, CarTitle) VALUES ($id, $title)"; is inside the foreach, means that for each pair of values from the form it'd insert to the database.
It doesn't do this. If I enter two or more CarIDs and CarTitles, only one pair of values gets saved to the database.
I'm sorry if I haven't explained this well enough, any questions please let me know.
Many thanks for your help in advance.

form.php 4.43KB
5 downloads Hi everyone, I'm new to this group and new to php. I have created a multi-part form that allows the user the option to add multiple input fields to a form to upload images. Here is the form structu Code: [Select] <form action="Scripts/processreports2.php" method="post" enctype="multipart/form-data" name="report_form" target="uploader" class="reportfrm"> <fieldset> <legend>Upload your images</legend> <ol id="add_images"> <li> <input type="file" class="input" name="files[]" /> </li> <li> <input type="file" class="input" name="files[]" /> </li> <li> <input type="file" class="input" name="files[]" /> </li> </ol> <input type="button" name="addFile" id="addFile" value="Add Another Image" onclick="window.addFile(this);"/> </fieldset> <p>* indicates a required field.</p> <input name="submit" type="submit" id="submit" value="Send Info!" /> </form> Through php a maximum of three input fields are fed into an array that checks to make sure that the uploaded files are images and not some other type of file. The uploading porition of this script works. Now I am trying to get the values of the input fields as a string and insert them into the database as one record. Let's say the user has three files they want to upload. I have managed to get the files as a string ie; file1.jpg, file2.jpg, file3.jpg but what is happening is that I am getting three separate records with file1.jpg, file2.jpg, file3.jpg in them. If the user has only two files to upload then I get two separate records with file1.jpg and file2.jpg in them. (Hope that makes sense). I want one record. I have been struggling with this since Monnday and while every day I get closer, this is as close as I can get. Below is the php code. #connect to the database mysql_connect("localhost", "root", ""); mysql_select_db("masscic"); //Upload Handler to check image types function is_image($file) { $file_types = array('jpeg', 'gif', 'bmp'); //acceptable file types if ($img = getimagesize($file)){ //echo '<pre>'; //print_r($_FILES); used for testing //print_r($img); used for testing if(in_array(str_replace('image/', '', $img['mime']), $file_types)) return $img; } return false; } //form submission handling if(isset($_POST['submit'])) { //file variables $fname = $_FILES['files']['name']; $ftype = $_FILES['files']['type']; $fsize = $_FILES['files']['size']; $tname = $_FILES['files']['tmp_name']; $ferror = $_FILES['files']['error']; $newDir = '../uploads/'; //relative to where this script file resides for($i = 0; $i < count($fname); $i++) { //echo 'File name ' . $fname[$i] . ' has size ' . $fsize[$i]; used for testing if ($ferror[$i] =='UPLOAD ERR OK' || $ferror[$i] ==0) { if(is_image($tname[$i])) { //append the tmp_name($tname) to the file name ($fname) and upload to the server move_uploaded_file($tname[$i], ($newDir.time().$fname[$i])); echo '<li><span class="success">'.$fname[$i].' -- image has been accepted<br></span></li>'; }else echo '<li><span class="error">'.$fname[$i].' -- is not an accepted file type<br></span></li>'; } if (is_array($fname)) $files = implode(', ',$fname); //else $files = $fname; $sqlInsert = mysql_query("INSERT INTO files (file_names) VALUES('$files')") or die (mysql_error()); } } Hey there...

I've spent the entire day googling and reading and to be honest I think I'm really over my head and need the assistance of someone experienced to advise the best way to go! I have a multi dimensional array that looks like (see below); the array is created by CodeIgniter's database library (the rows returned from a select query) but I think this is a generic PHP question as opposed to having anything to do with CI because it related to working with arrays. I'm wondering how I might go about searching the array below for the key problem_id and a value equal to a variable which I would provide. Then, when it finds an array with a the matching key and variable, it outputs the other values in that part of the array too. For example, using the sample data below. How would you recommend that I search the array for all the arrays that have the key problem_id and the value 3 and then have it output the value of the key problem_update_date and the value of the key problem_update_text. Then keep searching to find the next occurrence? Thanks in advance, as above, I've been searching really hard for the answer and believe i'm over my head! Output of print_r($updates); CI_DB_mysql_result Object ( [conn_id] => Resource id #30 [result_id] => Resource id #35 [result_array] => Array ( ) [result_object] => Array ( ) [current_row] => 0 [num_rows] => 5 [row_data] => ) Output of print_r($updates->result_array()); Array ( [0] => Array ( [problem_update_id] => 1 [problem_id] => 3 [problem_update_date] => 2010-10-01 [problem_update_text] => Some details about a paricular issue [problem_update_active] => 1 ) [1] => Array ( [problem_update_id] => 4 [problem_id] => 3 [problem_update_date] => 2010-10-01 [problem_update_text] => Another update about the problem with an ID of 3 [problem_update_active] => 1 ) [2] => Array ( [problem_update_id] => 5 [problem_id] => 4 [problem_update_date] => 2010-10-12 [problem_update_text] => An update about the problem with an ID of four [problem_update_active] => 1 ) [3] => Array ( [problem_update_id] => 6 [problem_id] => 4 [problem_update_date] => 2010-10-12 [problem_update_text] => An update about the problem with an ID of 6 [problem_update_active] => 1 ) [4] => Array ( [problem_update_id] => 7 [problem_id] => 3 [problem_update_date] => 2010-10-12 [problem_update_text] => Some new update about the problem with the ID of 3 [problem_update_active] => 1 ) ) Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. I have mysql select query shown below retrieving data from a database:
$sql = "
SELECT
student, sum( test_score ) as score
FROM
test
INNER JOIN
level
ON
test.level_id = level.level_id
GROUP BY
student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
while ($row = $result->fetch_array(MYSQLI_ASSOC))
{
var_dump($row);
}
}
On inspection of the retrieved array with var_dump(), i have these result below:
array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. I have an array created to control the down states of the my buttons in my navigation. Which is working well. This array will have quite a few strings in it before I'm done. I then want to conditionally load a CSS file for all the files in that array with the exception of two, is this possible? In plain in english I want to say If in array apart from these values then load my css file. My array (will have more values when complete) Code: [Select] $otherTitles = array('Product Selector', 'Avon Range', 'Knightsbridge Range', 'Kingston Range' ); My code to load a css file Code: [Select] <?php if (in_array($title, $otherTitles)) { ?> <link rel="stylesheet" type="text/css" href="homepage.css"/> <?php } ?> I want all titles in the otherTitles array to get this CSS file apart from two Product Selector and Avon Range. Thanks Richard I need to some how pull comma separated images $data[23] from this $data array and then put them into there own array so I can insert them into separate rows in a database. This is the provided array: $data[0] => VIN $data[1] => StockNumber ...(all the other number here) $data[23] => Image_URLs (comma seperated) $data[24] => Equipment // I need something like this (obviously doesn't work?!@#) $delimiter = ","; $img = explode($delimiter, $data[23]); foreach($img as $pic){ $sqlPic = "insert into class_prodimages (pid image rank) values('".$LastId['id']."', '$pic', '".rand(1,20)."')"; } Any help here?

I have the following construct of array now (schematics):
array[0] array[id] = "1" array[title] = "title" array[1] array[id] = "3" array[title] = "another title"Now what i want to do, is to assign the parent-array keys to the IDs of it's contents. This is what it should look like: array[1] array[id] = "1" array[title] = "title" array[3] array[id] = "3" array[title] = "another title"How do I do that again? I know I did this some years ago, but I can not remember how. Hi everyone. I have a registration form on my website that returns errors if the form isnt filled out correctly. An example of the code that returns the errors is: // if first name is blank return error if (!$first_name) { echo "Please enter your first name!<br />"; } // if first name contains invalid charcters return error if (preg_match('/[^a-zA-Z\s]/', $first_name)) { echo "Your first name contains invalid charcters!<br />"; } // set first name maximum length if ($first_name && !preg_match('/[^a-zA-Z0-9\s]/', $first_name)) { if (strlen($first_name) >25) { echo "The maximum length for first name is 25 characters!<br />"; } } Iv wrote it like this so that i can get multiple error messages appearing at the same time. When it comes to writing the form data to the database im using the following: if ($first_name && !preg_match('/[^a-zA-Z\s]/', $first_name) && strlen($first_name) <26 && $last_name && !preg_match('/[^a-zA-Z\s]/', $last_name) && strlen($last_name) <26 && $dob_day != "Day" && $dob_month != "Month" && $dob_year != "Year" && $gender != "Select" && $email && filter_var($email, FILTER_VALIDATE_EMAIL) && $confirm_email && $email == $confirm_email && $email_count == 0 && $town && !preg_match('/[^a-zA-Z0-9\s]/', $town) && strlen($town) < 26 && $location != "Select" && $postcode && !preg_match('/[^a-zA-Z0-9\s]/', $postcode) && $username && !preg_match('/[^a-zA-Z\s]/', $username) && strlen($username) >2 && strlen($username) <25 && $username_count == 0 && $password && strlen($password) >5 && strlen($password) <26 && $confirm_password && $password == $confirm_password) { // code to write to database here } I was wondering if there was a better way to confirm that all the form data is ok, and if so write the data to the database? Im new to php and would love to learn a way to make this easier instead of typing out loads of lines of code. Thanks to anyone that can help me.

I am having issues when attempting to submit a quantity (into table orders) using a form and validating it against an existing value (from table products), giving a response on whether there is sufficient quantity in the second table. I am then, in another page (same one performing the validations), attempting to then show a result based on the initial quantity entered, with a summary of the order details and calculation of the quantity * price to display a total as well. This has all been built from scratch, however I may have taken the wrong approach for these two pages... any assistance or insight as to where I am going wrong would be greatly appreciated. Here is the page I have placed the products, existing quantity and a text field they are able to enter their desired quantity: Code: [Select] <?php session_start(); require_once "../database/db.php"; require_once "../includes/functions.php"; $page_title = 'Product Catalogue'; include_once "header.php"; $conn = mysqli_connect ($dbhost, $dbuser, $dbpassword, $dbname); $query = "SELECT * from products"; $result = mysqli_query($conn, $query); if (!$result) { include_once "header.php"; die ("Error, could not query the database"); } else { $rows = mysqli_num_rows($result); if ($rows>0) { while ($row = mysqli_fetch_array($result)) { ?> <form> <br /> <br /> <br /> <table> <tr> <td style="width: 200px">Product Code:</td> <td><?php echo $row['ProductCode']; ?></td> </tr> <tr> <td>Product Name:</td> <td><?php echo $row['ProductName']; ?></td> </tr> <tr> <td>Product Description:</td> <td><?php echo $row['ProductDescription']; ?></td> </tr> <tr> <td>Product Colour:</td> <td><?php echo $row['ProductColour']; ?></td> </tr> <tr> <td>Product Price:</td> <td>$<?php echo number_format($row['ProductPrice'],2); ?></td> </tr> <tr> <td>Product Image:</td> <td><img src="<?php echo $row['ProductImagePath']?>"/></td> </tr> <tr> <td>Quantity in Stock:</td> <td><?php echo $row['ProductQuantity']; ?></td> </tr> </table> </form> <form method="post"action="processQuantity.php"> <table> <tr> <td style="width: 200px">Quantity:</td> <td><input type="number" name="Quantity" id="Quantity" value="<?php if (isset ($quantity)) echo $quantity; ?>"size = "20" /></td> <td><input type="submit" name="Purchase" value= "Purchase" /></td> </tr> </table> </form> <hr /> <?php } include "footer.html"; } } ?> Here is the page that I am using to validate the data as well as show a result based on the entered amount: Code: [Select] <?php session_start(); require_once "../includes/functions.php"; require_once "../database/db.php"; $quantity = $_POST['Quantity']; $productquantity = $_POST['ProductQuantity']; $orderid = $_POST['orderid']; $productcode = $_POST['productcode']; $productprice = $_POST['productprice']; $total = $quantity * $productprice; $error_message = ''; if ($error_message != '') { include_once "displayCatalogue-PlaceOrder.php"; exit(); $conn = mysqli_connect ($dbhost, $dbuser, $dbpassword, $dbname); if (!$conn) { echo "Error"; } else { //sanitise date $scustomerid = sanitiseMySQL($customerid); $sproductcode = sanitiseMySQL($productcode); $squantity = sanitiseMySQL($quantity); $sproductprice = sanitiseMySQL($productprice); $sorderdate = sanitiseMySQL($orderdate); $query = "select productquantity from products where productcode = '$sproductcode'"; $result = msqli_query ($conn, $query); $productquantity = mysqli_num_rows($result); if ($quantity < $productquantity) { $error_message = "You cannot order more than what is currently instock"; include_once "displayCatalogue-PlaceOrder.php"; exit (); } else { $row = mysqli_fetch_row($result); $query = "INSERT into orders (customerid, productcode, quantity, productprice, orderdate) values ('$scustomerid', $sproductcode', '$squantity', '$sproductprice', '$sorderdate')"; $result = mysqli_query($conn, $query); $row = mysqli_affected_rows($conn); if ($row > 0) { include "header.php";?> <h3>Order Confirmation</h3> <p>Thank you, your order is now being processed.</p> <table> <tr> <td style="width: 200px">Order Number:</td> <td><?php echo $orderid; ?></td> </tr> <tr> <td>Product Code:</td> <td><?php echo $productcode; ?></td> </tr><tr> <td>Quantity:</td> <td><?php echo $quantity; ?></td> </tr> <tr> <td>Price:</td> <td><?php echo $productPrice; ?></td> </tr> <tr> <td>Total Cost of Order:</td> <td><?php echo $total; ?></td> </tr> </table> <?php include "footer.html"; } else { $error_message ="Error placing your order, please try again"; include "displayCatalogue-PlaceOrder.php"; exit(); } } } } //this is used to validate the quantity entered against what is available in the database ?> Code: [Select] $product_id=$_GET['product']; $sql500="SELECT * FROM $tbl_name3 WHERE product_id='$product_id'"; $result500=mysql_query($sql500); $num_rows500=mysql_num_rows($result500); while($row500=mysql_fetch_array($result500)){ extract($row500); $review_product_rating_total=$review_product_rating; //What do I do here? } $average_rating=$review_product_rating_total/$num_rows500; I need a way to take a column of product ratings (0-5 in 1/2 increments), add them together, and divide by the number of rows taken from the database. I know how to get the number of rows with mysql_num_rows. But how would I add together the data from database? |
