I have this code:
<?php
$adm['web'] = "www.tuweb.com";
$adm['titulo'] = "Mi título web";
$campos = array('adm[web]','adm[titulo]');
for ($i=0; $i<count($campos); $i++) {
?>
/* add values in each field in the value="" */
<input type="text" name="<?php echo $campos[$i]; ?>" value="<?php echo ${$campos[$i]}; >"/>
<?php } ?>
The problem i have it´s when generate each field , in the value for each field no works value="" for add the value , only this problem
${$campos[$i]} evaluates to ${adm[web]}. You don't have a variable named "adm[web]". You have a variable named "adm", which has a key named "web". The variable variable interpolation cannot resolve this though.
The solution is to use $campos = array($adm['web'], $adm['titulo']) instead of the complicated workaround you're trying.
ONLY IF YOU to name the textfield as the array variable name and it value to be the value then this may be what you want
<?php
$adm['web'] = "www.tuweb.com";
$adm['titulo'] = "Mi título web";
$campos = array('adm[web]'=>$adm['web'], 'adm[titulo]'=>$adm['titulo']);
foreach($campos as $key=>$value){
?>
<input type="text" name="<?php echo $key; ?>" value="<?php echo $value; ?>" />
<?php } ?>
this will set adm[web] and adm[titulo] textfield names {sounds fishy}
better approach would be to
<?php
$adm['web'] = "www.tuweb.com";
$adm['titulo'] = "Mi título web";
$campos = $adm;
foreach($campos as $key=>$value){
?>
<input type="text" name="<?php echo $key; ?>" value="<?php echo $value; ?>" />
<?php } ?>
it will set the field names as the array keys i.e. 'web' and 'titulo'
hope this helps your case
Dirty though, but you could do:
echo eval('return $'. $campos[$i] . ';');
So it would be:
<input type="text" name="<?php echo $campos[$i]; ?>" value="<?php echo eval('return $'. $campos[$i] . ';');?>" />
<?php
echo eval('return $'.preg_replace('~(?<=\[)(.*?)(?=\])~',"'$1'",$campos[$i]).';')
?>
$camposArray ? why not using it directly ?
