Sorry guys i really didn't know what to put as a title for my problem:
So i have a page where data for a certain patient is displayed in a table. The user can update dosage and medication name for that certain patient.
Both update queries are working great! But, when the user clicks the update button the page reloads and the user can see that the data in the table has been updated. The dosage is doing this correctly but i having trouble figuring out how to get my medication name to display correctly on the page. AGAIN it is being UPDATED when i check my DB and if the user clicks the back button and clicks back on this certain patient he/she will see that the medication name has been changed but i want to show this right after the user clicks the update button.
I think i need to use a while loop to maybe pass the medication name but i am not quite sure????
In my code snippet that i am going to attach below I WILL PUT THE CODE in BOLD where i am doing the actual update and trying to pass the new medication name
Here is my code displaying the table and where i do the UPDATE queries:
Code:
<?php
include("config.php");
include("office-update.php");
include("lock.php");
if($role != 1)
{
header("Location: Login.php");
}
$id = $_GET['patient_id'];
$sql = "
SELECT patients.med_rec, patients.fname, patients.lname, prescriptions.start_date, medications.med_name, prescriptions.dose, UOM.name
FROM prescriptions, patients, medications, UOM
WHERE prescriptions.pat_id = patients.patient_id
AND medications.medication_id = prescriptions.med_id
AND UOM.unit_id = prescriptions.uom_id
AND patients.patient_id = $id;
";
#test if select statement works
$result = mysql_query( $sql );
$result or die("My query ($sql) failed." );
$row = mysql_fetch_array( $result);
// POST handler
$added = false;
if( isset($_POST['dose']) && isset($_POST['medications']) )
{
// instantiate data class
$postdata = new User( $_POST );
if( $postdata->validate() )
{
$added = $postdata->dose;
$postdata = NULL;
$dose = $_POST['dose'];
$med_id = $_POST['medications'];
$sql5 = "
UPDATE prescriptions
SET dose = $dose
WHERE prescriptions.pat_id = $id;
";
$sql6 = "
UPDATE prescriptions
SET med_id = $med_id
WHERE prescriptions.pat_id = $id;
";
$id = $_GET['patient_id'];
$sql = "
SELECT patients.med_rec, patients.fname, patients.lname, prescriptions.start_date, medications.med_name, prescriptions.dose, UOM.name
FROM prescriptions, patients, medications, UOM
WHERE prescriptions.pat_id = patients.patient_id
AND prescriptions.med_id = medications.medication_id
AND UOM.unit_id = prescriptions.uom_id
AND patients.patient_id = $id;
";
*********************************************************
$med_name = "SELECT med_name FROM medications WHERE medication_id = $med_id";
$name_result = mysql_query($med_name);
THIS IS WHERE I WANT TO GET THE MEDICATION NAME based on the med_id that is being picked in the dropbox that contains all the medication names
**********************************************************
$row['dose'] = $dose; //pass new dose
$row['med_name'] = $name_result; //pass new medication
***********I KNOW $name_result is wrong but it needs to be something else but i dont know what yet. ***************
$result5 = mysql_query( $sql5 )
or die( "Update failed ($sql5): " . mysql_error() );
$result6 = mysql_query( $sql6 )
or die( "Update failed ($sql6): " . mysql_error() );
}

I used a switch statement to test for what the user clicks on to sort, and then i pass the sql query.
