PHP - Check For "empty" String

Can someone please help me with an array problem i can not figure out.

I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array.

1, "mysql_field_name", "Title of form field"
2, "", ""

and so on

then the form will be shown based on the array.

I have the following draft code which I am working with.

any suggestions on how i may do this array ?

Code: [Select]
<?php
$options = array(
'1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'),
'2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'),
'3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'),
'4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'),
);


// $options = array(1 => "option1", "option2", "option3", "option4");

// the line above works but i want to include the name of the mysql field as well.

$userid = 1;

?>
<div style="align: center; margin: 12px; font-family:Tahoma;">
<br><br><?php
if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql.
$res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'");
foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); }
$ok_to_update = "no";
} elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data.
// error checking
// foreach($options as $key => $value) {
// $_POST[$i] = "";
// }
$ok_to_update = "yes";
}

if ($_POST['Update'] == "Update" && $ok_to_update == "yes") {
// $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database.
?><p><br><br><br>Thank you for updating</p><?php
} else {
?><form name="form1" method="post" action="">
<?php foreach($options as $key => $value) {
?><p><?php echo($value); ?>:&nbsp;<input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p>
<?php } ?>
<input name="Update" type="submit" value="Update">
</form>
<?php } ?>
</div>

What I am looking for is that if any field in a database is empty, the form comes back and puts in the word "empty" into the web page, but not the database.


I got this right now, it shows the first part fine, but the second part it doesn't show the "Empty" comment... I don't understand why... as far as I can tell the code is fine...

Code: [Select]
<?php
            //Nonconformity, Disposition, Comments and Comments & Additional Details
            echo '<div id="box3">';
                if (!empty($row['Nonconformity']) || !empty($row['Disposition']) || !empty($row['Comments']) || !empty($row['CommentsAdditional_Details'])) {
                    echo '<div id="non"><span class="b">Nonconformity:&nbsp;&nbsp;</span><br />' . $row['Nonconformity'] . '</div>';
                    echo '<div id="dis"><span class="b">Disposition:&nbsp;&nbsp;</span><br />' . $row['Disposition'] . '</div>';
                    echo '<div id="comm"><span class="b">Comments:&nbsp;&nbsp;</span><br />' . $row['Comments'] . '</div>';
                    echo '<div id="comma"><span class="b">Comments and/or Additional Details:&nbsp;&nbsp;</span><br />' . $row['CommentsAdditional_Details'] . '</div>';}
                        else
                            if (empty($row['Nonconformity']) || empty($row['Disposition']) || empty($row['Comments']) || empty($row['CommentsAdditional_Details'])) {
                                echo '<div id="non"><span class="b">Nonconformity:&nbsp;&nbsp;</span><br />Empty</div>';
                                echo '<div id="dis"><span class="b">Disposition:&nbsp;&nbsp;<br /></span>Empty</div>';
                                echo '<div id="comm"><span class="b">Comments:&nbsp;&nbsp;<br /></span>Empty</div>';
                                echo '<div id="comma"><span class="b">Comments and/or Additional Details:&nbsp;&nbsp;</span><br />Empty</div>';}
            echo '</div>';
?>

Hi,

bit stuck on how to find and replace "<" and ">" with "&lt;" and  "&gt;". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once

here's an example below

Code: [Select]
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
<h1>hello</h1>
</code>

the desired output would be:

<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<code>
&lt;h1&gt;hello&lt;/h1
</code>

help on this would be great

Cheers

Hi,
I need to call to this text to add a all with value "blank/empty" or "0" to the dropdownlist code below..
it should be inserted int the first position in the dropdownlist and have a value blank and call to this text from the language files:            
            $searchAll = gettext('_LANGUAGE_SEARCH_ALL',_LANGUAGE_SEARCH_ALL,false,false);
            example is:
            ratestitle=>0 gettext('_LANGUAGE_SEARCH_ALL',_LANGUAGE_SEARCH_ALL,false,false);
            the words it calls is "ALL" when the user selects or leaves the "ALL" in the list the value
             remains empty this allows the search to search everything..
basically im stuck how to get it in the dropdown list as the first default position:
can anyone help?

here is my code://this is a search function which calls to the field rate_title the text from the select box is matched to the database table and the search pages shows the search option is the search is successful.. I have 5 of these types of searches but cant give a broader search option to my users as the values must be selected to search--- i need the option "ALL" to have a "EMPTY" value or no value....
         

if (in_array("ratestitle",$searchOptions)&& $showSearchOptions )
            {
            if (empty($sch->filter['ratestitle']) )
               $selectOption=$output['LANGUAGE_SEARCH_RATESTITLE'];
            else
               $selectOption=$sch->filter['ratestitle'];
            $showButton=true;            
         $query = "SELECT DISTINCT rate_title FROM #__rates_table ORDER BY rate_title ASC";
         $dropDownList ="<select class=\"inputbox\" name=\"ratestitle\">";
         $ratesitles =doSelectSql($query);         
         foreach ($ratesitles as $ratetitle)
            {
            $selected="";
            $rate_title=$ratetitle->rate_title;
            if ($ratetitle==".$sch->filter['ratestitle'].")
               $selected="selected";
            $dropDownList .= "<option ".$selected." value=\"".$rate_title."\">".$rate_title."</option>";
            }
         $dropDownList.="</select>";
         $output['RATESTITLE']=$dropDownList;
            }
               

Hi guys

I am a newbie with PHP and I have been trying to solve this problem for 3 days..

Ive set up a booking form on my website to be sent directly to my email once the client clicked on the send button..
The problem I am having while checking these pages on wamp is that the booking form is ok but when I click on the send button the following message error appears
"Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\fluffy_paws\booking_form2.php on line 27"

When I check online I have this message "500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed."

Are my codes wrong???

My webhosting is Blacknight.com , Im on Windows Vista, my internet is a dongle with O2 ireland

Thanks for your help!
