Code Help.. If txt input box empty search X instead..

Posted on 16th Feb 2014 by admin

I am having a problem with my search script. At current it will simply search by a selected date which is a java based calendar that displays when using id='datedisplay' in the input form field below. What I want it to do is have an extra input text field box that can search for text/words within a table field. So my query would be something like Code: SELECT * FROM tbl_comments WHERE comments_date LIKE '%$search%' OR comments_content LIKE '%$textsearch%' ORDER BY comments_date DESC, comments_time DESC But now it gets tricky. I want it to work so if someone types something into the text input box, it will ignore the other input box that searches by date. And if the text input search box is empty, it will ignore the text input box and search only by the date input box.

I am assuming it's going to involve some if statements and posssible !empty and }else{ commands, I am just not 100% sure how to piece what I want together within my search code below.

Here is my form code:Code: echo "<form method='post' action='handover_index.php'>";
echo "<input type='text' name='search' id='datedisplay' style='width: 60px;' maxlength='10'> ";
echo "<input type='hidden' name='cmd' value='search' />";
echo " <input type='Submit' name='submit' value='Go!'>";
echo "</form>";

And here is my php code:Code: // ##### Search DB ##### Start ->
$str = str_replace("n", "<BR />", $str);
if (strlen($_POST["search"]) > 1 or strlen($_GET["search"]) > 1)
{
if(isset($_POST["search"])) $search=$_POST["search"];
if(isset($_GET["search"])) $search=$_GET["search"];

$result = mysql_query("SELECT * FROM tbl_comments WHERE comments_date LIKE '%$search%' ORDER BY comments_date DESC, comments_time DESC");

echo "<table width='98%' cellspacing='0' cellpadding='3' border='0'>";

$i = 0;
while($r=mysql_fetch_array($result))
{
$comments_id=$r["comments_id"];
$comments_date=$r["comments_date"];
$comments_time=$r["comments_time"];
$comments_user=$r["comments_user"];
$comments_content=str_replace("rn","
",$r[comments_content]);
$comments_updateuser=$r["comments_updateuser"];
$comments_updatedate=$r["comments_updatedate"];
$comments_updatetime=$r["comments_updatetime"];

list($thour, $tmin, $tsec) = explode(':', $comments_time);
list($uthour, $utmin, $utsec) = explode(':', $comments_updatetime);

if ($_GET[cmd]== "edit" and $_GET[comments_id] == $comments_id) {

$comments_content=str_replace("
","rn",$r[comments_content]);
echo "<tr>";
echo "<form action='handover_index.php' method='post'>";
