I have a table teamtrack_activity that holds id and activity_name.
I have table teamtrack_entry that holds all team daily entries. This table has a field "activity_id" that I want to store the teamtrack_activity id. I have this part working.
However I am having 2 issues:
Displaying activity_name instead of id. When I try to do this then activity_name gets passed and this of course doesn't work.
When I go back to edit the entry it does not show the value in the database. It just shows the select box anew.
if ($key == "activity_id")
{
$query="SELECT id, activity_name FROM teamtrack_activity Order By id";
$res = sql_query($query);
if ($res === FALSE)
{
trigger_error(sql_error(), E_USER_WARNING);
fatal_error(FALSE, get_vocab("fatal_db_error"));
}
$select_options["entry.$key"] = array();
for ($i = 0; ($row = sql_row_keyed($res, $i)); $i++)
{
$select_options["entry.$key"][$row['id']] = $row['id'];
}
}
Change:
$select_options["entry.$key"][$row['id']] = $row['id'];
into
$select_options["entry.$key"][$row['id']] = $row['activity_name'];
to get a dropdown with the activity ame, which submit the activity ID for your script.
Based on your comment;
It might be the parsing of your $select_options.
In a foreach loop you would want to
foreach($select_options["entry.$key"]) as $key => $label)
{
echo "<option value=".$key.">".$label."</option>";
}

I had cart data in session like product_id, product_name, product_price..... so there is multiple data in session with array it's not fixed..sometime single data and sometime morethan one..... but when customer check out.... I need to check each product with customers entered pincode …..and products have multiple or single pincode in table....so we can get them by session product_id ..... then want to check if those pin match with client/user pincode then store in new session and those products which are not match yet....also move in another new session..... or just want to display product like allowed or not allowed product for this pin
is there any way to make it simple ? i think it's work with foreach inside condtions and all..but still confused.....sorry for bad english !
i had just wrote little code but confused what to next ?
if (!empty($_SESSION["shopping_cart"])){
foreach ($_SESSION["shopping_cart"] as $keys => $value){
$pro_session_id = $_SESSION["shopping_cart"][$keys]['product_id'];
$select_price_data = mysql_query("select * from product_pincode where product_ID = '$pro_session_id'");
}
}
if (!empty($_SESSION["shopping_cart"])) {
foreach ($_SESSION["shopping_cart"] as $keys => $value) {
$pro_session_id = $_SESSION["shopping_cart"][$keys]['product_id'];
// echo $pro_session_id;
// echo "<br>";
// $select_pin_data = mysql_query("select * from product_pincode where product_ID = '$pro_session_id'");
$select_pin_query = "SELECT * FROM product_pincode WHERE product_ID = '$pro_session_id'";
$selected = mysql_query($select_pin_query, $con) or die(mysql_error($con));
$pin_val = array();
while ($get_pin_data = mysql_fetch_assoc($selected)) {
$pin_val[] = $get_pin_data;
}
foreach ($pin_val as $get_pin_data) {
if ($get_pin_data['pincode_number'] == $_SESSION["order_placement_details"][0]['user_pincode']) {
echo "Complete " . $get_pin_data['pincode_number'];
echo "<br>";
} else {
echo "unallowed" . $get_pin_data['pincode_number'];
echo "<br>";
}
}
}
Can anybody tell me what I'm doing wrong i want to update my Mysql table with 3 rows. I Selecting checkboxes and i press button then nothing happend with upadate of table. It's saving good id's to array, but update query doesen't work.
$s = mysql_query("SELECT data.id, data.sonda_data, data.type, odp.id, odp.sonda_data, odp.type, odp.wyniki, odp.idp FROM data,odp WHERE data.id=odp.idp");
$i=0;
$tab= array();
while ($row = mysql_fetch_row($s))
{
if ( (isset($_POST['pole'.$row[3]])) && (!isset($_SESSION['security'])) )
{
$id = $_POST['pole'.$row[3]]; // get id from radio boxes
$tab[i]=$id; // saving radio boxes id's to array
$i++; // increment array
// array look like example 8,11,10
if($i==3)
{
while($i>=1)
{
mysql_query("UPDATE odp SET wyniki = (wyniki + 1) WHERE 'id=$tab[$i]'");
$i=$i-1;
}
$_SESSION['security'] = true;
}
}
}
We have a PHP script that loops through many XML / CSV files from different websites. Right now we manage to build a good XML / CSV parser script.
The PHP script we wrote is looping though some BIG XML or CSV files. In these XML or CVS files contains Barcodes from different products.
Right now before the script starts I fill an array with the Product ID + Barcode from the MySQL like this:
function Barcodes_Array() {
$sql = "SELECT ProductId, Barcode FROM Products WHERE (Barcode <> '') ";
$res = mysql_query($sql);
while ($rijen = mysql_fetch_assoc($res)) {
$GLOBALS['arrBarcodes'][] = $rijen;
}
}
Each time we loop through the XML (or CSV) files we have to check if the Barcode exists in the array and return the Product ID.
For searching in the function:
$ProductId = SearchBarcodeProduct($EanNr, 'Barcode');
And yet the function:
function SearchBarcodeProduct($elem, $field)
{
$top = sizeof($GLOBALS['arrBarcodes']) - 1;
$bottom = 0;
$ProductId = 0;
while($bottom <= $top)
{
if($GLOBALS['arrBarcodes'][$bottom][$field] == $elem) {
return $GLOBALS['arrBarcodes'][$bottom]['ProductId'];
}
else {
if (is_array($GLOBALS['arrBarcodes'][$bottom][$field])) {
if (in_multiarray($elem, ($GLOBALS['arrBarcodes'][$bottom][$field]))) {
return $GLOBALS['arrBarcodes'][$bottom]['ProductId'];
}
}
}
$bottom++;
}
return $ProductId;
}
We fill in the array because it took forever each time we ask the MySQL Products Table.
My Question is now:
It still takes a VERY long time each time looping through the array of the barcodes. Is there a faster way for any other solutions maybe a different way then a array?
Can someone help please i am working like weeks on this stupid :) thing!
Why do you need 2 functions?
Try just one
function itemBarcode($id) {
$id = intval($id);
$sql = "SELECT ProductId, Barcode FROM Products WHERE ProductId = $id Barcode <> '') ";
$res = mysql_query($sql);
if ($row = mysql_fetch_assoc($res)) {
return $row['barcode'];
} else {
return 0;
}
}
Update if you need to search by barcode you can create another function:
function itemProduct($barcode) {
$sql = "SELECT ProductId, Barcode FROM Products WHERE Barcode = $barcode ";
$res = mysql_query($sql);
if ($row = mysql_fetch_assoc($res)) {
return $row['ProductId'];
} else {
return 0;
}
}
Sounds like you are missing an index on your Barcode column in your database.. A single row lookup using a presumably unique single indexed column should be blisteringly fast.
CREATE INDEX Barcode_Index ON Products (Barcode)
Then simply:
SELECT ProductId FROM Products WHERE Barcode = *INPUT*
You could also make the index UNIQUE if you NULL the Barcode where they currently = '' if there are more than one of these.
Another option is keying the array you have with the Barcode:
while ($rijen = mysql_fetch_assoc($res)) {
$GLOBALS['arrBarcodes'][$rijen['Barcode']] = $rijen;
}
or even just:
while ($rijen = mysql_fetch_assoc($res)) {
$GLOBALS['arrBarcodes'][$rijen['Barcode']] = $rijen['ProductId'];
}
Then you can do a straight look up:
$ProductId = isset($GLOBALS['arrBarcodes'][$Barcode])
?$GLOBALS['arrBarcodes'][$Barcode]['ProductId']
:0;
or:
$ProductId = isset($GLOBALS['arrBarcodes'][$Barcode])
?$GLOBALS['arrBarcodes'][$Barcode]
:0;
N.B Please read the warnings in the comments about use of $GLOBALS and mysql_query.
If you need it, store the barcodes array in an object or variable instead.
PDO is pretty handy, and I think it can also key your returned array for you on fetch.
I have a query which selects userid,messageid,statusid from tableA like following.
$qry = mssql_query('select userid,messageid,statusid from tableA');
if(mssql_num_rows($qry))
{
$data = mssql_fetch_array($qry)
{
//if(current_status_id column value != next_status_id column value)
$status = $data['statusid'];
}
}
I need to compare the value of current statusid column with the immediate next row statusid column like this if(current_status_id column value != next_status_id column value).Is this possible.Pls help me
$qry = mssql_query('select userid,messageid,statusid from tableA order by statusid');
while (($row=mssql_fetch_array($qry) !== FALSE) {
if (isset($previous) && $previous['statusid'] !== $row['statusid']) {
// do what you gotta do here
}
$previous = $row;
}
I added order by statusid to your SQL so that you do get an order set of data. And rather than trying to "look ahead" to the next row, the code above "looks back" to the previous row ... which is effectively the same. You've got the data of the two rows in $previous and $row so you should be able to do what you wanna do with $previous.
I have created an array and assigned the results into it.Then I used while loop and checked if the current element is not equal to next element.
$i=1;
while (($row = mssql_fetch_array($qry, MYSQL_ASSOC)) !== false)
{
$data_array[] = $row; // add the row in to the results (data) array
}
mssql_data_seek( $qry, 0 );
while($msgDetailChilds = mssql_fetch_array($qry)){
if($data_array[$i]['groupid']!=$data_array[$i-1]['groupid'])
{
//do stuff
}
}
So I have a tv show website and I created custom lists where you can add whatever tv shows you want.
There is one table called lists (with user_id, list_title) and another table called show_lists which contains (list_id, show_id).
So my PHP is there:
<?php
$findlistsq = $conn->prepare('SELECT * FROM show_lists, shows, lists
WHERE lists.user_id = :user_id AND
lists.list_id = show_lists.list_id AND
shows.id = show_lists.show_id');
$findlistsq->execute(array(':user_id' => 2));
$listscount = $findlistsq->rowCount();
echo $listscount;
$list = array();
while ($listarray = $findlistsq->fetch()) {
$list[$listarray['list_title']][$listarray['name']] = $listarray;
}
?>
<?php
foreach ($list as $key => $show) {
echo $key; //echo title of list
foreach ($show as $key => $value) {
echo $value['name']; //echo tv shows
;
}
}
?>
Basically, I create an array to join a list to its tv shows, display the title of the list and whatever it contains and so on. My question is: I want to display the list only if there is more than 3 shows (at least 3 different $value).
Can anybody tell me how I could do that ? Thanks!!
Edit: Also, there is slight chance that I might have overcomplicated this. Let me know if I did.
Your explanation of your data is not great, but you could try doing this in the SELECT statement, this will be faster than messing with arrays.
$findlistsq = $conn->prepare('SELECT *
FROM show_lists, shows, lists
WHERE
lists.user_id = :user_id AND
lists.list_id = show_lists.list_id AND
shows.id = show_lists.show_id AND
COUNT(DISTINCT shows.id) > 3');
This will count the DISTINCT (unique) show ids and only return you a data set if there are more than 3 DISTINCT show ids.
You will want to look into is_array() and count()
$list = array('show1','show2','show3');
if(is_array($list)){
if(count($list) > 3){
//more than 3 shows found, execute code!
}
}
