text forms

scuba

how can I make a text link pass a form to to the same page?

I've tried javascript but get different errors. Currently I tried:

$j = 1;
while ($j <= $page)
{
echo("<td><form name='jimmy' method='post' action='$PHP_SELF'>
<input type='hidden' name='list' value='$list'>
<a href=\"javascript:void(document.jimmy.submit())\">$j </a></form>
</td>");
$list = $list + 10;
$j++;

but that gives me an error too.

does anyone have example code for this.

Thanks in advance,
Steve

Either, I don't quite understand what you are trying to accomplish, or you're making this too hard.

Just write out a standard HTML form encapsulating your standard HTML inputs. For your text link use:

<a href="form.submit();">Submit Form</a>

Providing that this link is placed within your current form (Actually not sure if it matters. If you need to submit multiple forms and that doesn't work, you can use document.forms[x].submit where x is the array index for the current form.)

Hope that helps.

On second glance it appears I really didn't understand what you're trying to accomplish...why do you want the page to be submitted to itself 10 times for anyway ;-)...so I wasted your and my time.

scuba

This won't repeat ten times. Currently it only repeats twice so I have something like:

Page: 1 2

What I want to to click on the number 2 and have it pass the value $list which on the second time around should equal 10

then later on in a while loop I can show items between $list which should be 10 and $maxlist which would equal $list + 10;

basically I want this link which will be the text number 2 to pass the value $link to the same page called results.php

Hope that's clearer 🙂

Thanks,
Steve

Ah, you want page links via POST instead of GET. Sorry should have been a bit more thorough in reading your post...

In order to send unique values by submitting the form(s) via text link, what you need to do to is loop out a different form for each page link...which isn't gonna look too pretty as they will stack.

I woudl suggest either using buttons within one form (you can submit a unique value to the same form) or via GET which I think works best. Here's soem code I use for this same thing:

if(!isset($pg)){$pg=1;}

$curr_page = $pg;
$ub = $curr_page*$rows_per_page;
$start = $ub - $rows_per_page;

...query total count of records...

...query rows/page...

"...LIMIT $start,$rows_per_page"

for ($i=1;$i<=$pages;$i++){
echo " <a class=\"link\" href=\"$PHP_SELF?mode=$mode&pg=$i\">[page-$i]</a>\n";
if ($i%7==0){echo "<br>";}
}
if ($num_rows%$rows_per_page){
echo " <a class=\"link\" href=\"$PHP_SELF?mode=$mode&pg=$i\">[page-$i]</a>\n";
}

old newbie script....probably got a better one out there but this is all i could find at the moment.

bretticus

Whoops, got $pages from querying total records count....

Those bottom loops are not only embarrasing, but they are set up to break every seven links (for my own purposes on that particular script). I'm sure there's a better algorith for getting the page numbers.

Weedpacket

I prefer bretticus's suggestion of having the page numbering in the querystring (and hence using GET instead of POST). Just write e.g. ?link=3 in the querystring of link three's href attribute.

It could still be done in a POSTed form, without the breaking, if the links updated the list field, then submitted, so the final result looks like:

<form...>
<input type="hidden" name="list">
...
<a href="javascript:form.list.value=3;form.submit()">3</a>
...
</form>

Very bare, that. But it still looks like an excessively complicated way of providing page numbers...

And PS: could someone tell me why vBulletin has such a messy allergic reaction to the word "javascript"?

scuba

Thank you both for your help. I will try to implement your solutions into my script. This is the last thing I need to get working. Thanks again.

I apologize for being such a newbi at this.

Thanks,
Steve

scuba

right now i have:

echo("<form action='$PHP_SELF' name'list' method='post'>
<input type='hidden' name='list'>
<a href=\"javascript:form.list.value=10;form.submit()\">$j </a>");
$j++;

this is in a loop but i keep getting the error:

'form' is undefined' when I click on one of the links.

Any takes on this?

Thanks
Steve

bretticus

Arrrgghhh...sure you wanna use JavaScript still?? Well, if I can't change your mind, I can tell you what's up withe the JS error at least 😉

form is an alias to the current form and I haven't done my homework, but I don't think you'll get input values via form, best to refer to it directly with document I beleive...

you're almost naming your form: "list":

echo("<form action='$PHP_SELF' name'list' method='post'>

try "name='list' "

and rename either the hidden field or the form as they will be the same..."list"

<a href=\"javascript:document.<newname>.value=10;document.list.submit()\">$j </a>");

Should test this, but I guess you can do that ;-)

Cheers!

bretticus

CRUD...

New i shoudl have tested it...

Note update:

<a href=\"javascript:document.list.<newname>.value=10;document.list.submit()\">$j </a>");

Sorry for almost leading you astray

scuba

one last question for you if you don't mind. If I want to pass one more variable along with that, can I do something like:

this gives an error on page.

basically, $call is my query on the database and I want it to remember what it was querying to get the results it currently has.

Thanks,
Steve

bretticus

yeah, I assume you want your $call variable to pass in string data, just throw some single quotes around the variable.

Weedpacket

Problem is, $call might itself contain single quotes ... oh, this is getting too much for me.

Tell you what, split all that stuff in the href out into a JavaScript function - that will peel off two layers of quotes (one layer being the quotes around the href's attribute, and the other by escaping ?> out of PHP and into HTML <? except when PHP variables are being written. Perhaps have the $calls listed in an array, with indexes matching the possible values of $j.

Then in the href just contains a suitable call on this function - passing it $j - which can also do the submit.

May be a bit more tolerable when figuring out what needs to be escaped by how much.

bretticus

Good point...query will probably have single quotes already, However, JS does recognize escaped strings, I believe you'd get around it by using a addslashes($call) function call.

To tell you the truth, I think using JS to do this is somewhat impractical as you're depending on the client browser for processing and with the many flavors of browsers out there, that's always a bit risky. Querystrings would be much more dependible as HTML should always send the GET request without worrying about a client browser messing anything up before that happens.

And yes, I agree with Weedpacket, a manual will save you some time.
