Making the script echo only specific results

samanj · April 2, 2020

Hello community,

I am working on a database of specialties in the hospital I work.

The doctor's referral requests are sent to a mySQL database and I have, with the help of online guidance, produced a working php script that displays the information I need it to.

However, I need it a little bit more specific.

I intend to make multiple copies of this file for each specialty, so that when they open the file they only have the requests for that particular specialty.

My question is, with reference to my code below, can I make echo information so that online, for instance, if 'specialty1 = gastroenterology' (as in, that particular specialty that that referral request is for), then only the rows on the database that have that particular text are displayed only?

Hope that makes sense.

Code below for your reference and assistance is highly appreciated.

<!DOCTYPE html>
<html>
<head>
<title>Specialty Referral Form</title>
<style>
table {
border-collapse: collapse;
width: 100%;
color: #000000;
font-family: arial;
font-size: 10px;
text-align: center;
}
th {
background-color: #588c7e;
color: white;
}
tr:nth-child(even) {background-color: #f2f2f2}
</style>
</head>
<body>
<table>
<tr>
<th>Patient Details</th>
<th>Hospital Number</th>
<th>Date of Birth</th>
<th>Referred by:</th>
<th>New/Repeat Visit to Patient</th>
<th>Specialty</th>
<th>Admission Date</th>
<th>Too Ill for Clinic?</th>
<th>Diagnosis Aware?</th>
<th>Question</th>
<th>History</th>
<th>Medications</th>
<th>Examination</th>
<th>Results</th>
<th>WorkingDiagnosis</th>
<th>Investigation(s) Requested</th>
</tr>

<?php

$conn = mysqli_connect("localhost", "view", "", "referral");

// Check connection

if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT patientdetails, hospitalnumber, DoB, referral, admission, specialty1, admissiondate, illness, awareness, question, history, medications, examination, results, workingdiagnosis, investigations FROM referralform";
$result = $conn->query($sql);

if ($result->num_rows > 0) {

// output data of each row
while ($row = $result->fetch_assoc()) {
echo "<tr><td>" . $row["patientdetails"]. "</td><td>" . $row["hospitalnumber"] . "</td><td>" . $row["DoB"] . "</td><td>" 
. $row["referral"] . "</td><td>" . $row["admission"] . "</td><td>" . $row["specialty1"] . "</td><td>" . $row["admissiondate"] . "</td><td>"
. $row["illness"] . "</td><td>" . $row["awareness"] . "</td><td>" . $row["question"] . "</td><td>" . $row["history"] . "</td><td>"
 . $row["medications"] . "</td><td>" . $row["examination"] . "</td><td>" . $row["results"] . "</td><td>" . $row["workingdiagnosis"] . "</td><td>"
  . $row["investigations"]. "</td></tr>";
}
echo "</table>";
} else { echo "0 results"; }
$conn->close();
?>
</table>
</body>
</html>

I guess what I am looking for is something like echo specialty1 IF it writes a particular specialty and only that specialty.

Thank you.

no. you would use one file, that accepts a specialty id as an input, then uses a query with a WHERE clause in it to match the requested specialty information.

the specialties should be defined in a database table, with an id and a name. this will assign an id to each specialty. you would query this table to retrieve all the specialties to produce some sort of navigation/selection menu. when the visitor to the page picks a specialty via the navigation/selection menu, the submitted specialty id would be used in the code in the single file to cause the correct data to be retrieved and used to display the contents on the page.

The first step is to learn about getting data from the query string (aka $_GET). The URL to the page would be "script.php?specialty=whatever". One file handles everything, like mac_gyver said.

The second step is to take the value from the query string and use it with a prepared statement.

Ok thank you for the replies, it got the mental circuits in the brain working!

This is what I have been able to find and tweak based on both of your guidances (work in progress for all of the rows needed):

<!DOCTYPE html>
<html>
<head>
<title>Specialty Referral Form</title>
<style>
table {
width: 100%;
color: #000000;
font-family: arial;
font-size: 10px;
text-align: center;
}
th {
background-color: #588c7e;
color: white;
}
tr:nth-child(even) {background-color: #f2f2f2}
</style>
</head>
<body>
<table>
</tr>


<?php
$link = mysqli_connect("localhost", "root", "", "referral"); 
  
if($link === false){ 
    die("ERROR: Could not connect. " 
                . mysqli_connect_error()); 
} 
  
$sql = "SELECT * FROM referralcard WHERE hospitalnumber='345678'"; 
if($res = mysqli_query($link, $sql)){ 
    if(mysqli_num_rows($res) > 0){ 
        echo "<table>"; 
            echo "<tr>";  
                echo "<th>patientdetails</th>"; 
                echo "<th>hospitalnumber</th>"; 
                echo "<th>history</th>"; 
                echo "<th>comments</th>"; 
            echo "</tr>"; 
        while($row = mysqli_fetch_array($res)){ 
            echo "<tr>"; 
                echo "<td>" . $row['patientdetails'] . "</td>"; 
                echo "<td>" . $row['hospitalnumber'] . "</td>"; 
                echo "<td>" . $row['history'] . "</td>"; 
                echo "<td>" . $row['comments'] . "</td>"; 
            echo "</tr>"; 
        } 
        echo "</table>"; 
        mysqli_free_result($res); 
    } else{ 
        echo "No Matching records are found."; 
    } 
} else{ 
    echo "ERROR: Could not able to execute $sql. "  
                                . mysqli_error($link); 
} 
  
mysqli_close($link); 
?>

I appreciate you want propose that I make one file for all the different specialties.

My question is probably even more specific now, but any advice on how I can tailor this part:

$sql = "SELECT * FROM referralcard WHERE hospitalnumber='345678'";

i.e. the hospital number, in a text box, where I can type the number I want and that number appear as the hospital number I want where '345678' is currently in the code.

Then press submit to have the single row result I am looking for.

Would this be more in the realm of merging a html text box with php coding (e.g. is it using the POST function?)

Hope this makes sense.

Thanks as always.

Final update, I have made what I wanted to work, work. One page for everything.

Case closed. If anyone is interested in the code (albeit a very simple one), then feel free to get in touch
