hi guys im trying to use the the value of selectaircraft to search and display the result to textbox.. here is my code so far
<?php
require("dbc.php");
$getallconfig = mysql_query("SELECT * FROM aircrafttable WHERE aircraft LIKE 'PR200'");
while($viewallconfig= mysql_fetch_array($getallconfig)){
?>
<input type="text" name="aconfig "value="<?php echo $viewallconfig['config']; ?>" />
<?php } ?>
As you can see, I only put PR200 to search, my question is how can i use the select value instead? I also want the search query to happen everytime i click the select box.

Private Sub Combo3_Click()
adodc1.recorsource ="Select * from aircrafttable where aircraft = " & selectbox & "'"
adodc1.refresh
Text1.Text = Adodc1.Recordset("aircraft")
everytime i click combo/selectbox the query will perform and give different answer to textbox.

Answer 1

trigger submit on change of select box as below
<form action="path/to/your/query/file.php" method="post"> //if query in same page leave your action blank
<select name="selectaircraft" onchange="this.form.submi();">
<option id="0">-- Select Aircraft -- </option>
<?php
require("dbc.php");
$selected_aircraft=isset($_POST['selectaircraft'])?$_POST['selectaircraft']:"";
$getallaircraft = mysql_query("SELECT * FROM aircrafttable");
while($viewallaircraft = mysql_fetch_array($getallaircraft)){
$selectstr="";
if($selected_aircraft==$viewallaircraft['aircraft'] ){
$selectstr="selected='selected'";
}
?>
<option id="<?php echo $viewallaircraft['ID']; ?>" <?php echo $selectstr ?> >
<?php
echo $viewallaircraft['aircraft'] ?> </option>
<?php } ?>
</select>
</form>
and change you query as below:
<?php
require("dbc.php");
if(isset($_POST)){
$selectaircraft = mysql_real_escape_string($_POST['selectaircraft']);
$getallconfig = mysql_query("SELECT * FROM aircrafttable WHERE aircraft LIKE '{ $selectaircraft}'");
while($viewallconfig= mysql_fetch_array($getallconfig)){
?>
<input type="text" name="aconfig "value="<?php echo $viewallconfig['config']; ?>" />
<?php }
}?>
Update updated code to maintain state of select box.

Answer 2

Try like this;
$aircraft = mysql_real_escape_string($_POST['selectaircraft']); //or $_GET
$getallconfig = mysql_query("SELECT * FROM aircrafttable WHERE aircraft LIKE '".$aircraft."'");

Answer 3

You can keep the select box(1st) inside a form , on change submit the form to the next page .
And get the POST/GET value , and use it for select query for searching.
