Comparing values to give different outputs - php

Question

I have an Access database that has been converted to MySQL. I have a table, Contacts, with fields 'EmailAddress', 'HideEmailAddress', 'FaxNumber', 'HideFaxNumber', 'PhoneNumber', and 'HidePhoneNumber'. The hide fields are all checkboxes, so have values of 1 or 0, with 1 being TRUE.
I need, either in my MySQL Select statement or in my PHP query, to be able to not show the information if the hide field has a value of 1. Also, it's pretty common that only one of the three fields will be marked as hide, so I can't do a blanket "if any of these are 1 hide all of them.' I need to output the query to a webpage, and either show or hide the three fields above depending on the value of the hide field for each column. My SELECT statement is retrieving all six values, and the PHP is turning it into an array, but I don't think anything with array comparison will help here.
I just have no idea what I should be doing here. I've been searching for a couple of days now and nothing seems to come close to what I need. I have a VERY ad-hoc if-elseif-else running in my PHP loop in order to get it done by the deadline, but that requires 9 or 12 different statements, and I'm sure there's a better way to do this.
Here's my code. I've chopped it up a lot from the original query, but that query does work, so if there are typos here, it's from the chop-up. I just can't figure out how to suppress a field based on the value of another field. This is also why I have the two AS statements in the SELECT statement - in the original query, there's information coming from five different tables and there's "FaxNumber" and "EmailAddress" in both of them. I left the AS in just in case it changes things.

mysqli_query($dbc, $query);
if($r = mysqli_query($dbc, $query)) {
while ($row = mysqli_fetch_array($r)) {
if(($row['HidePhoneNumber'] == 1) && ($row['HideFaxNumber'] == 1)) {

'<br /><span class="strong">Direct Fax: </span>' . $row['ConFaxNumber'] . '<br /><span class="strong">Direct Email Address: </span>' . $row['ConEmailAddress'] . '</div>';}

<?php
$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME) or die('Error connecting to MySQL server.');
$query = 'SELECT Contact.CompanyID, Contact.WebContact, Contact.FirstName, Contact.LastName, Contact.WorkPhone, Contact.HidePhoneNumber, Contact.FaxNumber AS ConFaxNumber, Contact.HideFaxNumber, Contact.EmailAddress AS ConEmailAddress, Contact.HideEmailAddress FROM Contact WHERE TDAT_Contact.WebContact = "1"';
mysqli_query($dbc, $query);
if($r = mysqli_query($dbc, $query)) {
while ($row = mysqli_fetch_array($r)) {
echo '<hr><div align="query"><span class="strong">Contact:</span> ' . $row['FirstName'] . ' ' . $row['LastName'] . '<br />';
if ($row['HidePhoneNumber'] == 0) {
echo '<span class="strong">Direct Telephone: </span>' . $row['WorkPhone'] . '<br />';
}
if ($row['HideEmailAddress'] == 0) {
echo '<span class="strong">Direct Email Address: </span>' . $row['ConEmailAddress'] . '<br />';
}
if ($row['HideFaxNumber'] == 0) {
echo '<span class="strong">Direct Fax: </span>' . $row['ConFaxNumber'];
}
echo '</div>';
}
} else { // Query didn't run.
echo '<p style="color: red;">Could not retrieve the data because:<br />' . mysqli_error($dbc) . '.</p><p>The query being run was: ' . $query . '</p>';
}
mysqli_close($dbc); // Close the connection.

Answer 2

You can do it in mysql and avoid extra php coding
something like this assuming the Hide fields are booleans
$query = 'SELECT Contact.CompanyID, Contact.WebContact, Contact.FirstName,Contact.LastName,
case when Contact.HidePhoneNumber then '' else Contact.WorkPhone end as WorkPhone,
case when Contact.HideFaxNumber then '' else Contact.FaxNumber end AS ConFaxNumber,
case when Contact.HideEmailAddress then '' else Contact.EmailAddress and AS ConEmailAddress FROM Contact WHERE TDAT_Contact.WebContact = "1"';
then on php you just
if($r = mysqli_query($dbc, $query)) {
while ($row = mysqli_fetch_array($r)) {
echo '<hr><div align="query"><span class="strong">Contact:</span> ' . $row['FirstName'] . ' ' . $row['LastName'] . '<br /><span class="strong">Direct Telephone: </span>' . $row['WorkPhone'] . '<br /><span class="strong">Direct Fax: </span>' . $row['ConFaxNumber'] . '<br /><span class="strong">Direct Email Address: </span>' . $row['ConEmailAddress'] . '</div>';
}
}

Break your html output in small pieces, observe the common patterns, and factorize it in functions:
function hide($field, $label, $row){
if ($row['Hide'.$field] == 0)
echo '<span class="strong">'.$label.'</span>'.$row[$field].'<br/>';
}
$hiddenfields = array ('EmailAddress' => 'Email Address', 'PhoneNumber' => 'Direct Telephone' /* etc. */);
foreach($hiddenfields as $field => $label)
hide($field,$label,$row);
This should get you started.

Answer 4

You are using AND operator(($row['HidePhoneNumber'] == 1) && ($row['HideFaxNumber'] == 1) which means both conditions must be true to execute the conditional code.To resolve your problem you can use 'nested loop' within your while loop and check expressions for example:
$conditions=array("0"=>"phonenumber","1"=>"fax","2"=>"email") //associative array
for($i=0;$i<count($conditions);$i++){
if($row[$conditions[$i]]==1){
echo $row.[$conditions[$i]];
}
else{
echo "user doesn't want to share this information";
}
}
if condition returns 1 it will echo associated array member.
