Use a php function in echo statement

I've made this code, which disables a textbox if $TaxiDest has a value, however for my form to work i need this code to work [<?php phpfmg_hsc("field_17", ""); ?>] within the value tag of the textbox.

Here is the code im working with:

Code:

---

 
 <?php if($TaxiDest == "")
        {echo "<input type='text' name='field_17' id='field_17' value='phpfmg_hsc('field_17', '');' class='text_box'>";}
        else
        {echo "<input type='text' name='field_17' id='field_17' disabled='disabled' value='$TaxiDest' class='text_box'>";}
        ?>

---

by the way when i run the page [phpfmg_hsc(] is displayed in the textbox
ive made a few changes but still not got it working heres a live link

Thanks in advance,

There are a couple of ways; my preference is:

PHP Code:

---

<?php if($TaxiDest == ""): ?>
<input type='text' name='field_17' id='field_17' value='<?php echo phpfmg_hsc('field_17', '');?>' class='text_box'>
<?php else: ?>
<input type='text' name='field_17' id='field_17' disabled='disabled' value='<?php echo $TaxiDest;?>' class='text_box'>
<?php endif; ?>

---

This makes for the cleanest division of PHP from HTML. It works by exiting the PHP context as needed to output markup.

But this would also work:

PHP Code:

---

echo "<input type='text' name='field_17' id='field_17' value='".phpfmg_hsc('field_17', '')."' class='text_box'>"; 


---

It works by string concatenation.

...as would this, for example:

PHP Code:

---

echo "<input type='text' name='field_17' id='field_17' value='", phpfmg_hsc('field_17', ''), "' class='text_box'>"; 


---

It works by echoing multiple strings.

Thanks for your help, but i still cant get it working. The problem is that it doesn't fill field_17 in the email i receive, when i use the $TaxiDest (it shows on screen but not in email). It does work though when i type it manually.

Code:

---

    <?php if($TaxiDest == ""): ?>
        <input type='text' name='field_17' id='field_17' value='<?php phpfmg_hsc("field_17", "");?>' class='text_box'>
        <?php else: ?>
        <input type='text' name='field_17' id='field_17' disabled='disabled' value='<?php phpfmg_hsc("field_17", "$TaxiDest");?>' class='text_box'>
        <?php endif; ?>

---

I have the same problem with this line:

Code:

---

        <input type="text" name="field_28"  id="field_28" disabled="disabled" value="<?php  phpfmg_hsc("field_28", "$TaxiPrice"); ?>" class='text_box'>

---

Yet no problems here:

Code:

---

<input type="text" name="field_15"  id="field_15" value="<?php  phpfmg_hsc("field_15", ""); ?>" class='text_box'>

Thanks,

Assuming that phpfmg_hsc() returns a string, you'll need to preface it with echo in all of those cases:

PHP Code:

---

<?php echo phpfmg_hsc("field_17", "");?>

---

If that's not necessarily the case, then it might help to see the code of phpfmg_hsc().

Sorry for late reply, been busy this week.

I tried prefacing phpfmg_hsc() with echo and it still doesn't include it in the email.

Code:

---

function phpfmg_hsc($field, $default){
    echo isset($_POST[ $field ])
        ? HtmlSpecialChars( $_POST[ $field ] )
        : $default;
}

Since the function echos its result rather than returning one, you won't need to use echo before it.

You're saying that a field isn't appearing properly in an email - are you showing the code that is used for that email?

I've found the problem is due to the field being disabled, by removing the disabled property i receive its value in the email.

I think im going to have to hide the field rather than disable and use a div to display the value.

Thanks Chris1990.

Thanks for your help SambaNeko, ive got it working now.

Code:

---

    <?php if($TaxiDest == ""): ?>
        <input type='text' name='field_17' id='field_17' value='<?php phpfmg_hsc("field_17", "");?>' class='text_box'>
        <?php else: ?>
        <input type='text' name='field_17' id='field_17' style="visibility:hidden; display:none;" value='<?php phpfmg_hsc("field_17", $TaxiDest);?>' class='text_box'>
    <input type='text' name='field_17a' id='field_17a' disabled="disabled" value='<?php phpfmg_hsc("field_17", $TaxiDest);?>' class='text_box'>
        <?php endif; ?>
