Re: [PHP] PHP & MySQL Problem

I thought so, too. But the part where it receives the data is this:

$s_marke = $_POST['marke'];
$s_modell = $_POST['modell'];
$s_preis_von = $_POST['preis_von'];
$s_preis_bis = $_POST['preis_bis'];
$s_mileage_von = $_POST['mileage_from'];
$s_mileage_bis = $_POST['mileage_to'];
$s_ez_von = $_POST['ez_from'];
$s_ez_bis = $_POST['ez_bis'];
$s_search_text = $_POST['search_text'];
$s_cat = $_POST['cat'];
$kw_von = $_POST['kw_von'];
$kw_bis = $_POST['kw_bis'];

(part of it)

And this is the relevant part of the <form>

<select name="kw_von">
<option selected="selected" value="0">***</option>
<option value="44">44/60</option>

<option value="55">55/75</option>
<option value="66">66/90</option>
<option value="81">81/110</option>
<option value="92">92/125</option>
<option value="110">110/150</option>
<option value="147">147/200</option>
<option value="184">184/250</option>
<option value="220">220/300</option>
<option value="257">257/350</option>
</select>

The funny thing is that all vars are being received except for the last two:
$kw_von = $_POST['kw_von'];
$kw_bis = $_POST['kw_bis'];

I am soooo stuck here, it ain't even funny anymore *g* And my boss is, of course, waiting for a result. Howcome people don't get that programming sometimes really IS leaning back and closing your eyes *grrrrr* :oP

Thanks for trying to help me :o)

Right, here we go... this page has about 1000 lines of code, so here the
relevant stuff.

$s_query = "SELECT * FROM database WHERE
kategorie LIKE '$s_cat' AND
marke LIKE '$s_marke' AND
leistung_kw >= '$kw_von' AND leistung_kw <= '$kw_bis' AND
preis >= '$s_preis_von' AND
preis <= '$s_preis_bis'".$checkboxes.$sort_str;

I get the $checkboxes from the POST checkboxes, which looks like this (an
example):

$kraftstoffart = $_POST['fueltype'];
if($kraftstoffart == "3") {
$checkboxes .= "";
}elseif($kraftstoffart == "2") {
$checkboxes .= " AND kraftstoffart = '2'";
}elseif($kraftstoffart == "1") {
$checkboxes .= " AND kraftstoffart = '1'";
}

and the $sort_str comes in like

$sort_by = $_POST['sort_by'];
$desc_asc = $_POST['desc_asc'];
$sort_str = " ORDER BY ".$sort_by." ".$desc_asc;


The query then just goes like
$do_q = mysql_query($s_query) or die(mysql_error());

and that's it... no errors shown, just the regular output which I had
before I put the new fields in there. So no changes to what I've had
before... but there should be changes *g*

actually there seems to be no problem with your query (besides that you
should check posted values first in order to avoid SQL injection)

you said in your first letter that "$_POST['var'] don't reach the
script" - I would guess the relevant part is not the query but rather
the form itself...

I hope anybody can find some sense in what I'm writing here... hardly makes
sense to me :oP

Cheers!
