I am trying to pull dynamic content from a database based on the wildcard subdomain.
Please see the code below.
<?php
$data = $_GET['get'];
$data = addslashes(str_replace('-',' ',$data));
$town_result = $database->getData("select * from nationwide where town = '$data' ");
if( is_object( $town_result ) )
{
$area = $town_result->fetch_assoc();
}
else
{
$region_result = $database->getData("select * from nationwide where region = '$data' ");
if( !is_object( $region_result ) ) {
header('Location: http://example.com');
}
$area = $region_result->fetch_assoc();
$area['town'] = $area['region'];
}
?>
I have tried changing = '$data' "); to LIKE '%" . $data . "%'"); but this only pulls the first row in my database.
You can review how to use fetch_assoc to get associative records.
https://www.php.net/manual/en/mysqli-result.fetch-assoc.php
You can print $area, then you can verify either array count is 1 or more than 1.
Or best way, you can print sql query and run directly in your db.

I have a basic PHP page which searches a MySQL Database of retro ZX Spectrum magazine articles.
The address is [www.retroresource.co.uk][1]
The PHP Results Page is fine, in that it produced the results, but I would like to be able to group the results by 'fgames.fgname'
So for example if I searched for Dizzy
Dizzy (as a header)
Table with rows that have fgames.fgname = Dizzy
Spindizzy (as a header)
Table with rows that have fgames.fgname = Spindizzy
Treasure Island Dizzy (as a header)
Table with rows that have fgames.fgname = Treasure Island Dizzy
etc etc
I have googled and looked in a few of my text books, but am unable to see a solution. Any help much appreciated.

Amended Code after assistance (No results though)
<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
require( '../connect_db.php' ) ;
$query = $_GET['query'];
$min_length = 4;
// you can set minimum length of the query if you want
$query = strip_tags($query);
$query = mysqli_real_escape_string ($dbc,$query);
$q = "SELECT fgames.fgname, fgames.fgprorg, fgames.fgprbud, fgames.fgratng, fgames.fgprdsk, ftypes.fttname, frefs.fryymm, frefs.frpage, frefs.frissue, fmagzne.fmname, frefcde.ffname
FROM fgames, ftypes,frefs, fmagzne,frefcde
WHERE ftypes.fttype = fgames.fgtype

and frefs.frentry = frefcde.ffentry

$r = mysqli_query( $dbc , $q ) ;
$current_group = '';
while ( $row = mysqli_fetch_array( $r , MYSQLI_ASSOC ) )

mysqli_close( $dbc ) ;

There are two basic approaches.
Either load the query data into a two dimensional array and output with nested loop like this:
$array_for_output = array();
while($row = /* your query fetch mechanism here */) {
$array_for_output[$row['field_you_are_grouping_on']] = $row;
}
foreach($array_for_output as $table_name => $table_data) {
// output table header here
foreach($table_data as $table_row) {
// output individual row
}
// output table closure here
}
Or the other approach is to query using an ORDER BY clause on the field you are trying to group by and detect changes in the current group in single loop
$query = "
SELECT ...
FROM ...
WHERE ...
ORDER BY field_you_are_grouping_on, any_secondary_ordering_field_here ASC";
// execute query here
$current_group = '';
while ($row = /* your query fetch mechanism here */) {
if($row['field_you_are_grouping_on']) !== $current_group) {
// we have started a new group
if($current_group !== '') {
// this is not first table
// so output closure to previous table here
}
$current_group = $row['field_you_are_grouping_on'];
// output new table header here
}
// output row data here
}
// output closure to final table here
The second approach is usually preferable from a memory management standpoint (you don't have to store entire result set in memory at any point), but some beginning developers may not find this not as intuitive as the first method. The first method also may be more appropriate if you want to take the full result set and inject it into some sort of template that is used to render the display.
I have a huge table with some items. I want to retrive specific items from that table according with the players level of gaming . After the code extracts all the specific items i want to add them into an array ( in this case "$cart") . I want to update a mysql row into a varchar field the array separated by a comma ",";
I tried different methods of adding them into the database but something isn't working.
Heres my code :
$sql = mysql_query("select * from iteme where tip != 'Minereu' AND tip != 'Reteta' AND tip != 'Cooking' AND tip != 'Altele' AND tip != 'Potiuni' AND tip != 'Fragment' AND tip != 'Tools' AND tip != 'Medicina' ");
$numaratoare = 0;
$cart = array();
$nivel_player = mysql_query("select * from membri where id !=0 ");
while($informatie_player = mysql_fetch_array($nivel_player))
{
$nivel_actual_player = lvl($informatie_player['experienta']);
$shop_arme_plus_5 = $nivel_actual_player + 5 ;
if ($nivel_actual_player - 5 == 0 )
$shop_arme_minus_5 = $nivel_actual_player - 5 ;
else
$shop_arme_minus_5 = 0 ;
$shop_arme = mysql_query("select * from iteme where tip = 'Arme' AND level_minim < ".$shop_arme_plus_5." AND level_minim > ".$shop_arme_minus_5." AND vandabil = 1 ");
while($informatie = mysql_fetch_array($shop_arme)) {
$numaratoare ++;
//echo " ".$informatie['nume_ro']." , ";
array_push($cart, $informatie['obiect']);
}
mysql_query("INSERT INTO membri_shop_iteme set iteme_arme = ".$informatie["obiect"]." where id_jucator = ".$informatie_player['id']." "); // Here is the problem.
}
Where's the problem? I tried adding implode(', ', $cart); but still i can't add them into database.
Thanks for helping.
may be its string problem $informatie["obiect"] to $informatie['obiect']
mysql_query("INSERT INTO membri_shop_iteme set iteme_arme = ".$informatie['obiect']." where id_jucator = ".$informatie_player['id']." "); // Here is the problem.
to
$newObject=join(",",$cart);
mysql_query("UPDATE membri_shop_iteme SET iteme_arme = '".$newObject."' where id_jucator = ".$informatie_player['id']." "); // Here is the problem.
You use $informatie["obiect"] in your query, but you have to use $cart.
while($informatie = mysql_fetch_array($shop_arme)) {
$numaratoare ++;
array_push($cart, $informatie['obiect']);
}
mysql_query("UPDATE membri_shop_iteme
SET iteme_arme = '".implode("','", $cart)."'
WHERE id_jucator = '".$informatie_player['id']."'");
$query_country = "select abbr,full_name from Country";
$result_country = $db->query($query_country);//this is the first SQL
foreach ( $result_country as $row ){
echo '<optgroup label="' . $row['full_name'] . '">';
$abbr = $row['abbr'];
$query_airport = "select location from Airport where country_abbr = $abbr ";
$result_airport = $db_other->query($query_airport);//this is the second SQL
foreach ( $result_airport as $row_prime ){
echo '<option>'.$row_prime['location'].'</option>';
}
echo '</optgroup>';
}
As shown above, the 2nd SQL doesn't work.
I tried to NEW a PDO variable( $db_other ) in the 'config.php' file, but it still doesn't work.
My question is that how I can use the second SQL in a PHP loop.
The reason why I want to do this is that I need to make a selection table group by the 'Country name'.
try to quote your query variable and also use db object $db to run query
$query_airport = "select location from Airport where country_abbr = '$abbr' ";
$result_airport = $db->query($query_airport);
Also check $abbr have value so code looks like:-
if(!empty($abbr)) {
$query_airport = "select location from Airport where country_abbr = '$abbr' ";
$result_airport = $db->query($query_airport);
foreach ( $result_airport as $row_prime ){
echo '<option>'.$row_prime['location'].'</option>';
}
}
I have a database "test" the rows are username, category and testnr.
I want to use php to cross out any buttons/links on my website that user A has already done. For example username: userA finished testnr:1, so the link test1 in category A gets a line through. The following is as far as I got- (I am sorry, I am a beginner).
However, it would be terribly inefficient. I would have to "if" call for every category and, more annoyingly, testnr in each category. I also would need a next $text everytime, since otherwise every button would be crossed off.
There has to be a better way to do it, but I can not think of anything.
$curuser = $membersite->UserName();
$con = mysqli_connect("$host", "$username", "$password","$db_name");
$sql = "SELECT * FROM test WHERE user='$curuser'";
$text = "";
if ( !mysqli_query( $con,$sql ) ) {
die('Error: ' . mysqli_error($con));
}
$results = mysqli_query( $con, $sql );
while( $row = mysqli_fetch_array( $results ) ) {
$category = $row['category'];
$tnr = $row['testnr'];
if( $category = "Categname" && $tnr = 1 ) {
$text="style='text-decoration:line-through'";
}
}
mysqli_close( $con );
Problem is in your if case!!!
change this
if( $category = "Categname" && $tnr = 1 ) {
to
if( $category == "Categname" && $tnr == 1 ) {
You are assigning the values instead of checking!!! thats why all the links get line-through. See this ref
Im trying to set a A-Z filter for a table database in PHP. Below I have provided the code I have been working with. In between the bars is the code that I am trying to use. For some reason its saying I need to select a database and I thought I did that. Please any help would be appreciated.

Unless db_select is a custom function the function to call is *select_db*. Also I did not see a connection created but I assume that was done earlier.
