php to mysql data retrieval
Question
I am trying to retrieve data from mysql database that has 4 rows. I need to send this as an table in email using php. I have built a script for this, but the issue is the script is not emailing all the rows, its just emailing the last row or if i pass a specific parameter with "where" in db query.
Any help from anyone is appreciated. Thank you in advance.
Attached the db output and php code as well.
<?php
date_default_timezone_set('America/Los_Angeles');
$today = date("j-F-Y g:i:s a"); // March 10, 2001, 5:16 pm
// DB Connect.
$db_host = 'localhost'; // Server Name
$db_user = 'root'; // Username
$db_pass = 'test123#'; // Password
$db_name = 'util'; // Database Name
$conn = mysqli_connect($db_host, $db_user, $db_pass, $db_name);
if (!$conn) {
die ('Failed to connect to MySQL: ' . mysqli_connect_error());
}
$sql = "select * from srvr1";
$result = mysqli_query($conn, $sql);
if (!$result) {
die ('SQL Error: ' . mysqli_error($conn));
}
if(mysqli_num_rows($result) > 0){
while($row = mysqli_fetch_array($result)){
$File_system = $row[0];
$IP = $row[1];
$Capacity = $row[2];
$Available = $row[3];
$Used = $row[4];
$Percentage = $row[5];
# Compare Percentage and alert.
$subject = "Critical | FH NetApp-NetBackup Space Utilization..!";
$message1 = "

}
?>
I have been trying to shuffle around the loop in the code, it did not help.

Try and rearrange your code a little bit. First create the 'top' of the html, then go through all the results and append them to the html and then finish the html.
I haven't tested the code beneath but it should work :-)
<?php
date_default_timezone_set('America/Los_Angeles');
$today = date("j-F-Y g:i:s a"); // March 10, 2001, 5:16 pm

$db_host = 'localhost'; // Server Name
$db_user = 'root'; // Username
$db_pass = 'test123#'; // Password
$db_name = 'util'; // Database Name
$conn = mysqli_connect($db_host, $db_user, $db_pass, $db_name);
if (!$conn) {
die('Failed to connect to MySQL: ' . mysqli_connect_error());
}
$sql = "select * from srvr1";
$result = mysqli_query($conn, $sql);
if (!$result) {
die('SQL Error: ' . mysqli_error($conn));
}
if (mysqli_num_rows($result) > 0) {
$subject = "Critical | FH NetApp-NetBackup Space Utilization..!";

About conditional formatting
No worries. You can try and use nested ternaries (shorthand for if/else... to keep it short :-))
Example snippet from above code:
...
$Percentage = $row[5];
$color = ($Percentage > 90) ? '#FCE901' : (($Percentage > 85) ? '#FF0000' : '#00E526');
# Compare Percentage and alert.
$message1 .= "
<tr>
<td> $File_system </td>
<td> $IP </td>
<td> $Capacity </td>
<td> $Available </td>
<td> $Used </td>
<td style=\"background-color:$color\"> $Percentage </td>
</tr>";

The issue is somewhere on your database end. Based on your var_dump output:
object(mysqli_result)#2 (5) { ["current_field"]=> int(0) ["field_count"]=> int(6) ["lengths"]=> NULL ["num_rows"]=> int(1) ["type"]=> int(0) }
You only have 1 result being returned. You should start there. Maybe you're not referencing the table you think you are. Who knows right now, but you php looks fine. Investigate your DB

Your PHP is not fine stubben gave you the answer
<?php
date_default_timezone_set('America/Los_Angeles');
$today = date("j-F-Y g:i:s a"); // March 10, 2001, 5:16 pm
// DB Connect.
$db_host = 'localhost'; // Server Name
$db_user = 'root'; // Username
$db_pass = 'test123#'; // Password
$db_name = 'util'; // Database Name
$conn = mysqli_connect($db_host, $db_user, $db_pass, $db_name);
if (!$conn)
{
die ('Failed to connect to MySQL: ' . mysqli_connect_error());
}
$sql = "select * from srvr1";
$result = mysqli_query($conn, $sql);
if (!$result)
{
die ('SQL Error: ' . mysqli_error($conn));
}
if(mysqli_num_rows($result) > 0)
{
while($row = mysqli_fetch_array($result))
{
$File_system = $row[0];
$IP = $row[1];
$Capacity = $row[2];
$Available = $row[3];
$Used = $row[4];
$Percentage = $row[5];
Above You have a Percentage from 1 Row of Data Below you use that to decide the eMail subject - only 1 subject per email - so 1 row of data per email
# Compare Percentage and alert.
if($Percentage > 90)
{
$subject = "Critical | FH NetApp-NetBackup Space Utilization..!";
