Lo farei usando Ajax e JQuery. Dovresti fare 3 cose:aggiungere il codice Ajax/JQuery in head del documento, crea un file php per la connessione di Ajax e aggiungi onChange , id &value attributi ai campi.
Nel tuo <head></head> aggiungi questo javascript dopo il tuo <title></title> -
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">
function check(){
var pipeno = $('#pipeno').val();
if(pipeno != "pipeno"){
jQuery.ajax({
type: "POST",
url: "check.php",
data: 'pipeno='+pipeno,
cache: false,
success: function(response){
var response_array = JSON.parse(response);
$('#wallthickness').val(response_array['wallthickness']);
$('#jointno').val(response_array['jointno']);
$('#measuredlength').val(response_array['measuredlength']);
$('#serialno').val(response_array['serialno']);}
});
}
else{
$('#wallthickness').val('');
$('#jointno').val('');
$('#measuredlength').val('');
$('#serialno').val('');}
}
</script>
Quindi crea un file chiamato check.php con codice -
<?php
//Php Code to connect to postgresqldatabase
include ("connection.php");
// Code to pull data from the database and load onto the form
$pipeno = pg_escape_string($_POST['pipeno']);
$query = "SELECT * FROM fieldtally WHERE pipeno = $pipeno ";
$result = pg_query($db_handle,$query);
$row = pg_fetch_row($result))
$row_info = array('wallthickness'=>$row[1],'jointno'=>$row[2],'measuredlength'=>$row[3],'serialno'=>$row[4]);
$row_info = json_encode($row_info);
print_r($row_info);
?>
E infine, aggiungi id &value attributi ai campi del modulo (non modificare il file, aggiorna solo queste righe)
Select Pipe No:<select name="pipeno" id="pipeno" onChange="check()"><option value="pipeno"> --Select-- </option>
... (keep your database connection / how you create your dropdown, etc here, just edit the option below)
echo "<option value=\"$pipeno\"> $pipeno</option>";
... (keep your database connection / how you create your dropdown, etc. here)
</select>
...
Input Joint No: <input type="text" name="jointno" id="jointno">
Input Wall Thickness: <input type="text" name="wallthickness" id="wallthickness">
Input measured Length: <input type="text" name="measuredlength" id="measuredlength">
Input Serial No: <input type="text" name="serialno" id="serialno">
AGGIORNATO 19/10 A causa di codice modificato -
Ho inserito ancore numerate nel tuo codice e le note sono alla fine. Puoi farlo tutto in 2 file, ma il secondo file check1.php , può avere solo 1 query del database, altrimenti avrai errori nel tuo ajax.

Ecco i problemi-
1 - Sposta tutto <?php ?> script nella parte superiore della pagina. Questo:(1) ripulirà il tuo codice, (2) sarà in grado di elaborare tutte le query del database contemporaneamente.
2 - La tua richiesta per aggiornare fieldtally1 è ora fatto prima di ottenere i tuoi menu a discesa dal database.
3 - Per risolvere il tuo secondo problema after entering data into the input fields and click submit. it creates a new record in the database instead of populating the required columns in the database usa INSERT INTO ... VALUES ... ON DUPLICATE KEY UPDATE ... . Se pipeno è già nel database (poiché è una Primary Key ) UPDATE invece di INSERT .
4 - Ti consiglio di salvare il tuo error o success messaggio (#4a) e ripetilo nella parte superiore del tuo html (#4b).
5a - Sei passato da un pipeno hardcoded menu a discesa, torna al menu a discesa dinamico utilizzando la funzione. Quindi ti manca il javascript - onChange=check(); 5b - ora che stai creando il tuo pipeno &onChange=check(); dinamicamente, devi cambiare il tuo check() funzione per ottenere l'ID anche in modo dinamico.
6 - $PHP_SELF non è valido. Penso che stavi provando per $_SERVER['PHP_SELF'] , ma questo è facilmente hackerabile, quindi è meglio usare semplicemente action="" . [6.1,6.2,6.3]
7 - Quando esegui il tuo <select><option> stavi usando lo stesso value="" , ma ognuno deve essere diverso per ottenere il valore durante la pubblicazione. Inoltre, la maggior parte dei </option> ' sono stati scritti in modo errato come </optio> . [7.1,7.2,7.3]
8 - Se hai 3 moduli sulla stessa pagina, ognuno deve avere un nome diverso, altrimenti non sarai in grado di dire quale pulsante di invio è stato cliccato. [8.1,8.2,8.3]
9 - Nei primi due moduli mancavano i tag di chiusura - </td></tr></table></form> . [9.1, 9.2]
10 - Nei moduli 2 e 3 stai utilizzando id ' che sono usati nella prima forma. Questo non è valido come ogni id deve essere unico. [10.1,10.2]
11 - Il 3° modulo utilizza id="wallthickness" che è stato utilizzato nel modulo 2. vedi sopra su id unicità.
