How to make the user input stay on all the field that he/she already filled up? what I mean is sometime user have enter wrong input for particular field, but he has to re-enter all field again because of just one mistake in a field, say email field. How to make the user input stay in there if they already make correct input?

* in a form. Thanks...it will be good if some1 can send some coding as well.....i try to use history: go(-1) but don work..how?

ted_chou12 · January 10, 2007

for input:
[code]
<input type="text" value="<?php echo $string?>">
[/code]
for text areas:[code]
<textarea><?php echo $string?></textarea>
[/code]
and then set them to empty after data is correctly stored.

Someone did an example for me, this is extracted out of my page:
[code]
<select name="birthday" size="1">
<?php
$bdays = array('01','02','03','04','05','06','07','08','09','10','11','12','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28','29','30','31',);
$bday_select = "";
foreach ($bdays as $bdays)
{$bday_select .= '<option value="' . $bdays . '"';
if ($bdays == $birthday) {$bday_select .= ' selected';}
$bday_select .= '>' . $bdays . '</option>';}
echo "$bday_select";?>
</select>
[/code]
Where $birthday is the variable that you got from $birthday = $_POST['birthday'];
the rest just change them, but remember, keep the same variables the same name

erm..thanks...but is it all have to use foreach loop? for input text type also nit such coding? just to make the data stay after the javascript have detected invalid input.

ted_chou12 · January 10, 2007

sorry... i dont understand ???

taith · January 10, 2007

php runs before javascript... you set up the js using php, then the js can configure from there.

<form action="appointment2" method="POST" name="bkaddForm">

</SELECT>

it seems ur coding as same as this...The data never stay after the user has selected it on screen..ok..let me explain in details....

The Date require user to input Day Month Year separtely as shown above. Let say the user forgot to enter Month and year, only Day...Javascript will display some some error message (validation). After clicking 'OK" of the message pop up, the data of the Day should remain there.

Just like when u fill a form to register..just because email invalid, u don have 2 re-enter again for the other field that already correctly enter.

ted_chou12 · January 10, 2007

What I think is easier if you used all php, so smt like this:
[code]
if ($year == "" or $month == "") {echo "You have not fill in the required fields";}
[/code]

tauchai83 · January 10, 2007

i Already have all the require validation.

<?php

if($Year=='' and $Month=='' and $Day ==''){
echo "<script>alert(\" Sorry! Please fill in your booking date.\");history.go(-1)</script>";
}else

if($Year=='' and $Month==''){
echo "<script>alert(\" Sorry! Please fill in your booking Month and Year.\");history.go(-1)</script>";
}else

if($Year=='' and $Day==''){
echo "<script>alert(\" Sorry! Please fill in your booking Day and Year.\");history.go(-1)</script>";
}else

if($Month=='' and $Day==''){
echo "<script>alert(\" Sorry! Please fill in your booking Day and Month.\");history.go(-1)</script>";
}else

if($Year == ''){
echo "<script>alert(\" Sorry! Please fill in your booking year.\");history.go(-1)</script>";
}else
if($Month == ''){
echo "<script>alert(\" Sorry! Please fill in your booking month.\");history.go(-1)</script>";
}else
if($Day == ''){
echo "<script>alert(\" Sorry! Please fill in your booking day.\");history.go(-1)</script>";
}else
if($Time == ''){
echo "<script>alert(\" Sorry! Please fill in your booking time.\");history.go(-1)</script>";
}

ted_chou12 · January 10, 2007

okay, thats cool, does the <?php echo $string?> thing works for textareas and input fields? or they dont work at all as well, or is it just the drop down box which doesnt work?
Ted

tauchai83 · January 10, 2007

<td width="40%"><b>First Name</b> :</td>
<td width="50%"> <input type="text" name="f_name" value="<?php echo $row["First_name"]; ?>"> <font color="#FF0000" size="2">(*) Require field</font></td>
<td width="10%"></td>

the value of this "echo" is retrive from Database Mysql. ur method echo $string is retrieved frm DB or from the user input on the form?

ted_chou12 · January 10, 2007

[code]<?php if(isset($_POST['submit'])){
$name = $_POST['name'];
$birthday = $_POST['birthday'];
if ($birthday == "" or $name == "") {echo"<p>(Required field(s) are left blank)</p>";$invalid = TRUE;}
if ($invalid == FALSE) {require("mysqlconnection.php");
$insert = mysql_query("INSERT INTO user(name, birthday) VALUES('$name', '$birthday')")//or other types of storing you wish.
$birthday = ""; $name = "";//set them empty after storage.
}}
//form below:?>
<form name="test" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<input name="username" value="<?php echo"$name"?>" type="text" size="30" maxlength="20" />
<select name="birthday" size="1">
<?php $bdays = array('01','02','03','04','05','06','07','08','09','10','11','12','13','14','15','16', '17','18','19','20','21','22','23','24','25','26','27','28','29','30','31',);
$bday_select = "";
foreach ($bdays as $bdays)
{$bday_select .= '<option value="' . $bdays . '"';
if ($bdays == $birthday) {$bday_select .= ' selected';}
$bday_select .= '>' . $bdays . '</option>';}
echo"$bday_select";?>
</select>
</form>
[/code]
