Combining a collection of variables into one variable.

[Toolmaster]

Hi guys back again with more problems.

I would like to store a collection of variables into one whole variable.

 

This code below shows drop down boxes, which contain the days, months and years.

I would like to store this information into one variable, how would I do this?

 

For example if the user selects 02, March, 2007 then I would like this information to be stored into the database. How can I store each value in the seperate drop down lists into one whole variable?

 

Would appreciate the help, thanks.

 

<?php

/* create form containing date selection list */

echo "<form action=’processform.php’ method=’POST’>\n";

 

/* build selection list for the day */

$todayDay= date("d",$today); //get the day from $today

echo "<p>Please select a date: \n";

echo "<select name=’dateDay’>\n";

for ($n=1;$n<=31;$n++)

{

echo " <option value=$n";

if ($todayDay == $n )

{

echo " selected";

}

echo "> $n\n";

}

echo "</select>\n";

 

/* build selection list for the month */

$todayMO = date("m",$today); //get the month from $today

echo "<select name=’dateMO’>\n";

for ($n=$todayMO+0;$n<=$todayMO+1;$n++)

{

echo "<option value=$n\n";

if ($todayMO == $n)

{echo " selected";

}

echo "> $monthName[$n]\n";

}

echo "</select>";

 

/* build selection list for the year */

$startYr = date("Y", $today); //get the year from $today

echo "<select name=’dateYr’>\n";

for ($n=$startYr;$n<=$startYr+1;$n++)

{

echo " <option value=$n";

if ($startYr == $n )

{

echo " selected";

}

echo "> $n\n";

}

echo "</select>\n";

echo $appointment_date = 'dateDay', 'dateMO',  'dateYr'; (i've attempted it this way, but it doesn't work. )

echo "</form>\n";

?>

.= this syntax adds things to an existing variable

 

 

for example:

 

$variable = "Hello";

 

$variable .= " World";

 

echo $variable;

 

 

you should get this: Hello World

$appoitment_date=array("dateDay"=>$_POST['dateDay'],"dateMo"=>$_POST['dateMo'],"dateYr"=>$_POST['dateYr']);

I suggest you read about Arrays

In the OP's original example ... why not simply use the form POSTed data to generate the date in the (useful) form yyyy-mm-dd since that's ideal for simple comparisons.

 

In your sample code, the selected date is never going to show since the values selected are not available until the submit - which your form doesn't even contain!! - is pressed.  Then you can abstract the individual values of DateDatm dateMO, and dateYr from the POSTed array and use mktime() to generate the date.
