form submition

[rhock_95]

Is there a simple way to prevent an html form from being submitted (without javascript) if no text is entered?

 

<form action="peop_search.php" method="post">
<input type="text" name="query" />
<input type="submit">
</form>

 

If an invalid query is entered it prints the message below but if nothing is enterd it prints all the records

 

if ($numrows == 0){
echo("No results found matching your query - $query");

 

Is there any way to amend this to echo the above if nothing is entered?

if (isset($_POST)) {

//do any kind of manipulation and output with the posted form data

//like checking for correct/empty form fields

} else {

//if nothing is being posted, the form is then displayed

}

 

PHP is server side, you can only "change" things once a page has been loaded/reloaded, so once the form has been posted you can then decide what to do with the data, Javascript on the other hand can stop the form from being submitted in real time, but i assum ethat is really now what u want, u can still have the form submitted, but just give the impression of it not being submitted if incorrect data has been submitted and u can just simply redisplay the form like it was never submitted

 

perception is the keyword

Thanks for the reply...

 

//like checking for correct/empty form fields

 

Ho do I do this? this is actually the crux of what I am seeking

[dsaba]

$var = "";

 

if (empty($var)) {

echo 'its empty';

}

 

if ($var == "") {

echo 'its empty';

}

 

if (strlen($var) == 0) {

echo 'its empty';

}

 

if ($var != "correct data") {

echo 'u get it';

}

Thanks again for the efforts... but the script still retrieves all the records...it also prints out ALL the messages... any ideas?

 

 

[rarebit]

can u show code?

It would be helpful to see more code, especially the query you're using.

 

You might try using something like this.

 

if(!isset($_POST['query']) || $_POST['query'] == "")
{
 echo "No results found matching your query - $query";
}
else
{
 // process query using $_POST['query']
}

<?php


if ($_POST[variable]=="") { $error[variable]="Please enter the variable";} else { unset($error[variable]);}

if ($error){ ?>

html form


<?php 

}else{ insert record ;}

?>

[rhock_95]

Thanks for the reply...

 

with that I get nothing but line errors (like a missing curly bracket) but I can't seem to resolve the errors

 

exactly how would I incorporate this into my script?

[rarebit]

Would help to see the script!

 // process query using $_POST['query']
}

 

This Almost works... what it does is print the "No results found matching your query" above each record...but it is still printing all the records

[JJohnsenDK]

post all your code mate... we most see the posts you are making too..

[rhock_95]

I would like to oblige but the script is so loaded with my own personal comments it would take me half an hour just to strip all the comments...

 

is there a particula part of the script that would help specifically?

 

the script queries a database for a single column but has pagination results...

[darkfreaks]

did u use my code? please list the errors wrong with it.

 

 

[rhock_95]

Yes thanks for the efforts...

 

it throws numorious line errors starting with

 

}else{ insert record ;}

[darkfreaks]

lol show me your code only way we can help.

[rhock_95]

what part of the script?

[darkfreaks]

show me everything before the html form php wise

[rhock_95]

sorry I can't do that...without stripping all the comments

 

the html form is a different page/file  the action of the form(page) calls the script

 

some of the suggestions in already posted print the error message but the script still returns all the records

[darkfreaks]

what do you want it to error? like if you dont fill in the form or what?

[darkfreaks]

try

 

 

<?php
if  empty($_POST[variable]||$_POST[variable2]) { echo "sorry you must fill in the form";}

?>

[rhock_95]

exactly if the form is submitted with no entry in the form field display message

[darkfreaks]

try my above code ^

[rhock_95]

try

 

 

<?php
if  empty($_POST[variable]||$_POST[variable2]) { echo "sorry you must fill in the form";}

?>

 

that throws a line error regardless of where in the script I set  it

 

Parse error: parse error, expecting `'(''

 

 

[darkfreaks]

please specify the line of the error and paste that line here
