Adding date on html page by using PHP and checking for appropriate date

<table>

<tr>

<td>Date </td>

<td>

<select size="1" name="year">

<?php

$years1=range(date("Y"),2030);

foreach ($years1 as $value) {

echo '<option value="'.$value.'">'.$value.'</option>\n';

} 

?>

</select>

<select size="1" name="month">

<?php

$months=range(1,12);

foreach ($months as $value) {

echo '<option value="'.$value.'">'.$value.'</option>\n';}

?>

</select>

<select size="1" name="date" >

<?php

$days=range(1,31);

foreach ($days as $value) {

echo '<option value="'.$value.'">'.$value.'</option>\n';

}

?>

</select>

</td>

</tr>

</table>

In this table, we have taken three select tags. In it, we created a PHP array using range() function. After that, we have assigned each value to option in foreach loop.
Now we will check for appropriate date format.


if(!checkdate($_POST['returnmonth'],$_POST['returndate'],$_POST['returnyear']))
{echo "<script>alert('Wrong date entered !')</script>";}

checkdate takes three parameters for a month, day, and year. The parameters should be provided in the order mentioned above. The function returns a boolean value either true or false.
