Keeping data in fields after submit

[trevor4370]

I have looked and I can not see thread about this, but I am sure there must be something .... if there is please point me in that direction. Also, just learning pHp .....

 

I have a form that is validated, so the fields don't get deleted when the form is submitted and checked. I insert value="<?=$gender;?>"  (for example) in the Gender field. This seems to work with standard textfields, but what about drop down lists etc ..... it doesn't seem to work for them ... where should the value field go in these?

For drop down menues you have to test if your var is equal to the option value and use SELECTED in your option tag

 

print ("<select name='contact_time' class='FormEntry' id='contact_time'>
<option value='0'"); if ($contact_time=="0"){echo "selected";} print (">(Select a time)</option>
<option value='Anytime'"); if ($contact_time=="Anytime"){echo "selected";} print (">Anytime</option>
<option value='Morning'"); if ($contact_time=="Morning"){echo "selected";} print (">Morning</option>
<option value='Afternoon'"); if ($contact_time=="Afternoon"){echo "selected";} print (">Afternoon</option>
<option value='Evening'"); if ($contact_time=="Evening"){echo "selected";} print (">Evening</option>
</select>");

Thank you for you quick reply. I tried this but it does not seem to work .... it displays OK and everything, but once the Submit button is clicked and the form valilates, the entry reverts back to (Select a time), doesn't matter what is selected.

 

Am I doing something wrong ???? I am using the same code you gave me.

 

<?php

print ("<select name='contact_time' class='FormEntry' id='contact_time' >

<option value='0'"); if ($contact_time=="0"){echo "selected";} print (">(Select a time)</option>

<option value='Anytime'"); if ($contact_time=="Anytime"){echo "selected";} print (">Anytime</option>

<option value='Morning'"); if ($contact_time=="Morning"){echo "selected";} print (">Morning</option>

<option value='Afternoon'"); if ($contact_time=="Afternoon"){echo "selected";} print (">Afternoon</option>

<option value='Evening'"); if ($contact_time=="Evening"){echo "selected";} print (">Evening</option>

</select>");

 

  ?>

in this exemple i am using $contact_time ... did you $contact_time=$_POST[contact_time]; ?

[Barand]

I prefer to to use an array. (The same technique works if you are loading the options from a database instead of an array)

 

<?php 
$options = array('Anytime', 'Morning', 'Afternoon', 'Evening');

echo "<select name='contact_time'>";
echo "<option value='0'>(select time)</option>";

foreach ($options as $opt)
{
    $sel = $opt==$_POST['contact_time'] ? 'selected' : '';
    echo "<option value='$opt' $sel>$opt</option>"; 
}
echo '</select>';
?>

yeah much more clean thx

[shank888]

i go

 

<form>

User: <input type='text name='user' value='$_POST['user]' />

</form>

 

or sumfin like that i cant remember

[drisate]

your way out off topic shank888  lol

[shank888]

Lol okay haha I dunno what I am doing. But i use if (isset ($_POST['submit'] {  for my form action.

 

then i can make it return me back to my form.

 

and then once it returns me the form data will be filled out like it was left.

 

print 'Username: <input type='text' name='username' size='20' value="' .$_POST[username']. '" />':

 

edit:

 

Okay I quit. I am wayy off topic

[trevor4370]

OK .. yes I did forget - $contact_time=$_POST[contact_time];

 

Thanks, and thanks Barand for your code .... I will try this as well. Just one more thing (and there always is) ... checkboxes ... how are these accomplished ... value="<?=$xxxxx;?>"  doesn't work here either.

 

I have learnt more on pHp today, thanks heaps .... more for the snippet box.

 

 

[drisate]

same thing if the value of the check box is equal to the value you received you echo "checked";

[trevor4370]

OK .... I get it now.

 

Now if I want an error message ... the following should work ... but doesn't.

 

<?php

$options = array('Male','Female');

 

echo "<select name='gendar'>";

echo "<option value=''></option>";

 

foreach ($options as $opt)

{

    $sel = $opt==$_POST['gendar'] ? 'selected' : '';

    echo "<option value='$opt' $sel>$opt</option>";

}

echo '</select>';

 

 

if (trim($gendar)==''){

  print " Please enter your Gendar ";

    }else{

  print " ";

    }

?>

 

What am I doing wrong, it should work .... I have used this for textfields ???

 

Thanks

[shank888]

what is there to check if you can't submit the code. I assume that is the only code you have?

 

 

[trevor4370]

No .... actually is is a large form ...

 

$firstname  = $_POST['firstname'];

$surname = $_POST['surname'];

$gender= $_POST['gender'];

$gender2= $_POST['gender'];

$age_on_12_05_07= $_POST['age_on_12_05_07'];

$day= $_POST['day'];

$month= $_POST['month'];

$year= $_POST['year'];

$address= $_POST['address'];

$town= $_POST['town'];

$postcode= $_POST['postcode'];

$state= $_POST['state'];

$phone= $_POST['phone'];

$Emergency_contact_name= $_POST['Emergency_contact_name'];

$Emergency_contact_phone= $_POST['Emergency_contact_phone'];

$phone_home= $_POST['phone_home'];

$phone_work= $_POST['phone_work'];

$phone_mobile= $_POST['phone_mobile'];

$email= $_POST['email'];

$email2= $_POST['email2'];

$medical= $_POST['medical'];

$finish_time_mar= $_POST['finish_time_mar'];

$finish_time_5km= $_POST['finish_time_5km'];

$finish_time_1500m= $_POST['finish_time_1500m'];

$race1= $_POST['race1'];

$race2= $_POST['race2'];

$race3= $_POST['race3'];

$race4= $_POST['race4'];

$race5= $_POST['race5'];

$race2_15under= $_POST['race2_15under'];

$race3_15under= $_POST['race3_15under'];

$race5_15under= $_POST['race5_15under'];

$Pay= $_POST['Pay'];

$Terms= $_post['Terms'];

$caps= $_POST['caps'];

$hats_sm= $_POST['hats_sm'];

$hats_med= $_POST['hats_med'];

$hats_lg= $_POST['hats_lg'];

$dinner_adults= $_POST['dinner_adults'];

$dinner_children= $_POST['dinner_children'];

$Bus_from_Yangan= $_POST['Bus_from_Yangan'];

$Bus_start_Killarney= $_POST['Bus_start_Killarney'];

$Bus_from_Falls= $_POST['Bus_from_Falls'];

$race1_name= "Half Marathon";

$race2_name= "4.6km Cross-Country";

$race3_name= "5000m";

$race4_name= "10km Ascent ";

$race5_name= "1500m";

$race2_15under_name= "4.6km X-Country Under 15";

$race3_15under_name= "5000m under 15";

$race5_15under_name= "1500m Under 15";

 

/*Formula for total costs  */

 

$CapsCost= $caps*10;

$hats_sm_cost= $hats_sm*10;

$hats_med_cost= $hats_med*10;

$hats_lg_cost= $hats_lg*10;

$dinner_adults_cost=$dinner_adults*15;

$dinner_children_cost=$dinner_children*7;

$TotalCost= $race1+$race2+$race3+$race4+$race5+$CapsCost+$hats_sm_cost+$hats_med_cost+$hats_lg_cost+$dinner_adults_cost+$dinner_children_cost+$race2_15under+$race3_15under+$race5_15under;

 

Just makes it easier for the user to find out what they have not filled in .... I have found not all users know what they are doing on the Internet .... even when completing forms .... I have tried to make them simple, but someone alway has a problem. Just trying to be end user friendly.

 

Thanks

Okay well my keyboard is acting up aagin so I am not sure if this script works. infact I am 90% sure it wont missing some quotes and stuff. But I think you may try somethign like:

<?php
//filename is test.php in this case and we are doing the full script on one page
echo "<html>
<head></head>
<body>
<form action='test.php' method='post'>
<select name='gender'>
	<option value=' ' selected='$_POST['gender']'> $_POST['gender']</option>
	<option value='1'>Female</option>
	<option value='2'>Male</option>
</select>
<input type='submit' value='Submit'> <input type='reset' value='Reset'>
</form>";

if (isset($_POST['submit'])) {
$female = 1;
$male = 2;
if ($_POST['gender'] != $female || $_POST['gender'] != $male) {
¨	echo "please enter a gender";
} else {
	echo "echo or whatever you wanna do here";
}
}
?>
</body>
</html> 

[Barand]

if ($_POST['gender'] != $female || $_POST['gender'] != $male) {

 

should be

 

if ($_POST['gender'] != $female && $_POST['gender'] != $male) {

[shank888]

Hmm makes sences lol

 

|| means or

&& means and

 

 

[Barand]

if ($_POST['gender'] != $female || $_POST['gender'] != $male) {

¨ echo "please enter a gender";

} else {

echo "echo or whatever you wanna do here";

}

 

Suppose 1 (male) is entered.

 

in that case, gender is not equal to female, so it asks for a gender.

 

If 2 (female) is entered, gender is not equal to male, so it asks for a gender.

 

 

If you use && as suggested it will ask for gender if it is not 1 AND it is not 2.

 

You need to get a handle on Boolean logic

 

NOT (A || B) == NOT A && NOT B

[shank888]

Normally I do. Haha, but like i said I'm 90% sure it wont work.

thank you tho.

another easier way to look at things
