I'm having trouble writing an if else statement. Considering that I've been doing so for years in ColdFusion, this make me feel very stupid.
Here's the task.
I need to pull first name, last name, email, co-chair status from a database and return the results. However not everyone has an email, so I need a statement that will include a mailto link for those that have emails, and exclude a mailto link for those that don't.
Here's the code I'm using that includes the mailto link for all.
What adjustments do I need to make?
thanks,
david
<?php do { ?>
<?php echo $row_GetMembers['BACmember_First']; ?> <?php echo $row_GetMembers['BACmember_Last']; ?>
<?php /*START_PHP_SIRFCIT*/ if ($row_GetMembers['BACmember_CoChair']=="Yes"){ ?>
<strong> Co-Chair</strong>
<?php } /*END_PHP_SIRFCIT*/ ?><br />
<?php } while ($row_GetMembers = mysql_fetch_assoc($GetMembers)); ?>
This is the line of code you want to optionally display as a link (split for readability):
<a href="mailto:<?php echo $row_GetMembers['BACmember_Email']; ?>">
<?php echo $row_GetMembers['BACmember_First']; ?>
<?php echo $row_GetMembers['BACmember_Last']; ?>
</a>
You'll want something like this instead:
<?php if (!empty($row_GetMembers['BACmember_Email'])): ?>
<a href='mailto:<?php echo $row_GetMembers['BACmember_Email']?>>
<?php echo $row_GetMembers['BACmember_First']; ?>
<?php echo $row_GetMembers['BACmember_Last']; ?>
</a>
<?php else: ?>
<?php echo $row_GetMembers['BACmember_First']; ?>
<?php echo $row_GetMembers['BACmember_Last']; ?>
<?php endif; ?>
If the email field isn't empty (the ! negates the result, so we're checking if it isn't empty), it prints the first and last name inside an anchor tag. If it is empty, it prints the name without it.
A more elegant solution may be to provide the email address as a separate field or link, as opposed to having a list of some names that are links and some that aren't.

Im trying to send the patient ID through a hyperlink, tho while it redirects to the correct page it is not sending the information.
<a href="./patientrecord.php?patient_id="<?php $row["patient_id"]?>><?php echo $row["surname"];?></a>
Please make sure you are going to echo the variable
Echoing a variable:
<?= $echoable_variable_here ?> // Use <?= ?> tags
or
<?php echo $echoable_variable_here ?> // Use echo inside <?php ?> tags
Edit: You have placed echo outside the href attribute tag
Therefore,
Change this:
<a href="./patientrecord.php?patient_id="<?php $row["patient_id"]?>><?php echo $row["surname"];?></a>
to:
<?php echo $row["surname"];?>
or to:
<?php echo $row["surname"];?>
I need help writing a php echo that checks if two cells are the same in two tables.
The cells are:
posts>id and reblogs>newid
I have the following code to start with:
<?php if(!empty($reblogDetails->newid)): ?>
<table><tr><td>
<?php echo $newid;?>
</td><tr></table>
<?php else: ?>
original upload
<?php endif ?>
which I borrowed from another snippet but isn't working.
can anyone help?
Your question is not completely clear, but I am assuming you want to show the table with an anchor tag only if the posts->id is equal to the reblogDetails->newid? If that is the case the code you would want would be more like the below.
<?php if(!empty($reblogDetails->newid) && $posts->id == $reblogDetails->newid): ?>
<table><tr><td>
<?php echo $newid;?>
</td><tr></table>
<?php else: ?>
original upload
<?php endif ?>
That being said I doubt your anchor tag is doing what you want. I would anticipate it creating an anchor that looks something like
12
I have a MySQL database storing some basic user info, so: name, email, and two phone numbers. I want to make a page with dynamic php text showing the users info, but in the database only one phone number is required. On the page I have:
<p id="first"> Some non-dynamic text </p>
<p> <?php echo $row_rsCustomer['first_name']; ?> </p>
<p> <?php echo $row_rsCustomer['email']; ?> </p>
<p> <?php echo $row_rsCustomer['phone_one']; ?> </p>
<p id="phonetwo"> <?php echo $row_rsCustomer['phone_two']; ?> </p>
<p id="second"> Some non-dynamic text </p>
I dont want the #second to be pushed down if the #phonetwo is empty. I was thinking of using some javascript like this:
if( #phonetwo.innerhtml == ""){
#phonetwo.style.display="none";
But I was wondering if there's a way to do this using php? The javascript solution will work I suppose, but I'm pretty sure I've seen somewhere a more "correct" way to do this, I just don't remember what it was nor can I find it anywhere.
Just wrap the paragraph in a conditional
<?php if(isset($row_rsCustomer['phone_two']) && $row_rsCustomer['phone_two']):?>
<p id="phonetwo"> <?php echo $row_rsCustomer['phone_two']; ?> </p>
<?php endif?>
<?php if (!empty($row_rsCustomer['phone_two'])) { ?>
<p id="phonetwo"><?php echo $row_rsCustomer['phone_two'] ?></p>
<?php } ?>
Just follow this pattern anytime you need to hide HTML from PHP:
<? if (your condition) { ?>
Html
<? } ?>
It is much better than doing it in JS since it does't send any data to the browser.
First check is it empty or not
<?php if(!empty($row_rsCustomer['phone_two'])) { ?>
<p id="phonetwo"> <?php echo $row_rsCustomer['phone_two']; ?> </p>
<?php } ?>
check if $row_rsCustomer['phone_two'] is not empty and then display your <p> :
<?php if (isset($row_rsCustomer['phone_two'])) { ?>
<p id="phonetwo"><?php echo $row_rsCustomer['phone_two'] ?></p>
<?php } ?>
I have a WordPress site in which I have added a few extra fields for Author contact fields. Some people are going to use Google plus but some will not. I don't want to have an empty paragraph tag etc. I can't seem to figure out how to write an if statement that works. This is what I was working with. Thanks for your time.
<?php if(get_the_author_meta('google')) ?> { ?>
<p><?php the_author_meta('google'); ?></p>
<?php }
else {
// do nothing
} endif; ?>
<?php if(get_the_author_meta('google')): ?>
<p><?php the_author_meta('google'); ?></p>
<?php
else:
// do nothing
endif; ?>
Did you try this? Also, your code has the opening brace for 'if' without a php tag.
try this - and put a class of some sort on there to ensure it's not showing up in the spots where it's not filled in - a border or something?
<?php if (get_the_author_meta('google')) { ?>
<p class="error"><?php the_author_meta('google') ?></p>
<?php }
else {
// do nothing
} ?>
This seems to work. Maybe it's the endif ?
I'm using the following section of code to display some icons on our Magento store with the idea being if there is nothing added in the icons section it shouldn't display, for some reason this isn't working...it is displaying a division as if something is there but there is actually nothing.
<?php
if($_helper->productAttribute($_product,($_product->geticons()), 'icons') !== null):
?>
<div class="product-icons">
<?php echo $_helper->productAttribute($_product,($_product->geticons()), 'icons') ?>
</div>
<?php endif; ?>
It needs to show Icons if they are coded in the attribute field and then hide the division if there is nothing added.
I've worked out that the code is returning a value of string(0) what do I need to change in my coding to get the desired effect?
Here's the thing you need, and you don't need call the same functionality twice to get the empty result. Define your variable and check if it is empty (null, undefined or false) or not
<?php $icons = $_helper->productAttribute($_product,($_product->getIcons()), 'icons');?>
<?php if(!empty($icons)):?>
<div class="product-icons">
<?php echo $icons;?>
</div>
<?php endif;?>
this could be even better solution as it wont call the helper unless there are icons defined but you first have to try it out on your codebase.
<?php if($_product->getIcons()):?>
<div class="product-icons">
<?php echo $_helper->productAttribute($_product,($_product->getIcons()), 'icons') ?>
</div>
<?php endif; ?>
and please check if it isn't a typo and it really is:
$_product->geticons()
or should it be
$_product->getIcons()
Something like:
<?php
if($_helper->productAttribute($_product,($_product->geticons()), 'icons'))
{
echo "<div class=\"product-icons\">";
echo $_helper->productAttribute($_product,($_product->geticons()), 'icons');
echo "</div>";
}
?>
would be better!
try
<?php
if(!empty($_helper->productAttribute($_product,($_product->geticons()), 'icons')))
{
echo "<div class=\"product-icons\">";
echo $_helper->productAttribute($_product,($_product->geticons()), 'icons');
echo "</div>";
}
?>
