mySQL表上的PHP脚本：FROM_UNIXTIME和INTO OUTFILE问题

Question

This is my first php script for a mysql table.

mySQL table looks as below :

From that table i would like to generate a dynamic HTML table with the following requirements :

• HTML table sorted ASC by NEXT_EVENT
• HTML table gets a new column showing NEXT_EVENT value as human readable datetime.

Once the table is sorted i need to output ID and NEXT_EVENT values from the very first row to a TXT file, the 2 values will be comma separared.

I tryed to write a PHP script, but it get errors.

Sorting ASC looks working properly, but conversion with FROM UNIXTIME does not and file output won't work either.

mysql table's name is : 'webpilot'

$result = mysqli_query($conn, "SELECT * FROM webpilot ORDER BY NEXT_EVENT ASC");

$table = '<table>
            <tr>
                <th>ID</th>
                <th>NAME</th>
                <th>NEXT_EVENT</th>
            </tr>';

if ($result) {
    while ($row = mysqli_fetch_assoc($result)) {
        mysqli_query($conn, "SELECT FROM_UNIXTIME(".$row['NEXT_EVENT'].") as $datetime");               

        $table .= '<tr>
                    <td>'.$row['ID'].'</td>
                    <td>'.$row['NAME'].'</td>
                    <td>'.$row['NEXT_EVENT'].'</td>
                    <td>'.$datetime.'</td>
                   </tr>';
    }
} else {
    $table .= '<tr><td colspan="3">No date found</td></tr>';
}
$table .= '</table>';
echo $table;

$fileoutput = mysql_query($conn, "SELECT ID,NAME,NEXT_EVENT FROM webpilot INTO OUTFILE '/next_event.txt' LINES TERMINATED BY '\n'");

The live result can be seen here : http://s529471052.onlinehome.fr/bs3/gpio/dyntable.php

but i had to comment out the following line, as it reports an error avoiding the rest of script to be run and php webpage to be displayed.

mysqli_query($conn,"SELECT FROM_UNIXTIME(.$row['NEXT_EVENT']) as $datetime");

Line 203 is related to that line :

$fileoutput = mysql_query($conn,"SELECT ID,NAME,NEXT_EVENT FROM webpilot INTO OUTFILE '/next_event.txt' LINES TERMINATED BY '\n'"); 

Would you please show me how to get expected result.

Answer 1

can you check mysql function is wrong mysql_query is there u know that one you need to change mysqli_query

$fileoutput = mysqli_query($conn,"SELECT ID,NAME,NEXT_EVENT FROM webpilot INTO `OUTFILE '/next_event.txt' LINES TERMINATED BY '\n'");`

and

$datetime you need to assign values. Example like $datetime=date("Ymd H:i:s")

Answer 2

HTML table sorted ASC by NEXT_EVENT (You are correct)

SELECT * FROM webpilot ORDER BY NEXT_EVENT ASC

HTML table gets a new column showing NEXT_EVENT value as human readable datetime. (You can try to more easy way, do inside php)

$getDateTime = mysqli_query($conn,"SELECT NEXT_EVENT FROM webpilot where NEXT_EVENT=".$row['NEXT_EVENT'].");

$rowDateTime = mysqli_fetch_array($getDateTime );

$datetime = date("Y-m-d H:i:s", $rowDateTime('NEXT_EVENT'));

MYSQL ways:

SELECT ID, FAVORITE, NAME, ORDERTYPE, STATE, LAST_EVENT RECCURENCY, FROM_UNIXTIME(timestamp) as datetime FROM webpilot ORDER BY timestamp ASC

so your this code mysqli_query($conn, "SELECT FROM_UNIXTIME(".$row['NEXT_EVENT'].") as $datetime"); can be remove.
