PHP Form: yeni bilgiler girerken yeni bir tablo satırı ekleyerek sonuçlar aldıktan sonra

1 Cevap

Although probarly quite simple, i cannot seem to find the following.
The form takes certain data, and then represents the data in a table.

Next step i click the hyperlink that takes me back to the form.
Now my question is how exactly do i make it possible when filling in the same form again so both results are displayed in the same table?
Then filling in a other form with data adds another row and so on.

Saygılar.

Sizin oturum değişkenleri sadece girilen verilerin son parça saklamak olacaktır. Oldukça basit değişkenler olarak oturumda bunları depolamak yerine, oturumda bir dizi koyarak deneyin. Sonra form tekrar gönderildiğinde, bu diziler için başka bir girdi ekleyin. Bu şekilde daha önce orada ne üzerine yazmaz.

ETA:

Eğer oturum değişkenleri set nerede Page 1, bu deneyin:

$_SESSION["standnaam"][]=$standnaam;
$_SESSION["oppervlakte"][]=$oppervlakte;
$_SESSION["verdieping"][]=$verdieping;
$_SESSION["telefoon"][]=$telefoon;
$_SESSION["netwerk"][]=$netwerk;

Sayfa 2, tablo satırları yazmak nerede, bu deneyin:

for($i = 0; $i < count($standnaam); $i++) {
    echo "<tr>";     
        echo "<td>".$standnaam[$i]."</td>";
        echo "<td>".$oppervlakte[$i]."</td>";
        echo "<td>".$verdieping[$i]."</td>";
        echo "<td>".$telefoon[$i]."</td>";
        echo "<td>".$netwerk[$i]."</td>";
        echo "<td>".$totalePrijs[$i]."</td>";
    echo "</tr>";
}

Ben dokunsa bunu düşünüyorum.
